Transmission malfunction: The torque converter, which replaces the manual clutch in a car with an automatic transmission, is in charge of transferring power. The converter won’t function properly if the torque converter is damaged or if the transmission fluid level is low; as a result, the vehicle won’t be able to sustain power at low speeds, which results in the engine cutting out. This problem can also be brought on by a broken torque converter solenoid or TCS.
The fuel pump is in charge of moving fuel from the tank to the engine regardless of low fuel pressure, filthy or damaged fuel injectors, or a faulty fuel pump. Low fuel pressure from a damaged fuel pump can lead to an uneven stream of fuel being delivered to the engine. This doesn’t matter as much at high speeds, but at low speeds, even a little interruption in the fuel delivery might cause the engine to stall. A precise amount of fuel is sprayed out by the fuel injectors, and at the right moment, it is ignited by the spark plugs. Over time, injectors can get clogged or unclean, which causes irregular spray or no spray at all.
Bad oxygen sensor or mass flow sensor: The oxygen sensors and mass flow sensor let the vehicle adjust the air-to-fuel ratio by detecting how much oxygen is entering the fuel stream. Your vehicle won’t run as efficiently if the oxygen level is too high or too low. The car will continue to run at driving speeds, just like with low fuel pressure, but this insufficient power won’t be able to fuel the vehicle when it slows down.
Wires that are loose or rusted in the wiring harness: An ignition that fires inconsistently will cause an easily stalled engine. The vehicle can quickly lose voltage and won’t have the power it needs to remain running when you slow down if the wires are not in steady, dependable, and consistent contact with the ignition circuit.
Idle air control actuator malfunction: During idling, the engine’s RPMs are controlled by the idle air control actuator. The electronic control unit (ECU) sends information to this actuator, letting it know what RPM to keep the engine at for a secure and smooth idle. When the actuator is broken, the engine is not sent a signal for the idle speed and shuts off.
EGR valve obstruction or restriction: Depending on whether the EGR valve is jammed open or closed, a clogged, unclean, or damaged EGR valve might cause your automobile to stall, idle incorrectly, or sputter.

Low on fuel
Three things are required for your engine to function properly: air, gasoline, and spark. One of these three things was unexpectedly taken away if your engine is functioning great and then just stops. Typically, it is fuel.
Lack of gasoline is the primary cause of vehicle shut-offs while moving. An empty fuel tank and a fuel gauge that is less accurate than it appears to be are the most likely causes. Bang on the tank even if it claims there is fuel inside. It is most likely empty if it sounds hollow.
Nissan Altima 2005 issue with engine shutting off suddenly
Hello, my name is and I own a 2005 Nissan Altima. This automobile has been mine since 2008. I looked into 2005 service records before making my purchase. There have been a staggering number of problems with this car. The most recent of them is the “grey” area of the ecm problem in conjunction with the well-known p0355 & p0131 camshaft crankshaft malfunction. Being an engineer, I am completely familiar with a vehicle’s mechanics. The design of this sensor was flawed from the start since oil might get inside and cause a short that would disable the entire car while it was moving. I actually went through this, and it was terrifying. Nissan initiated a recall to reprogram the ecm to identify the “faulty” crankshaft sensor part in an effort to rectify the problem on the cheap. Nissan, however, refused to include the warrantied replacement of the flawed crankshaft sensor design in order to save millions of dollars (magnet sensor). The “new & improved version” of the sensor would cost the consumer (me) between $300 and $450 to replace. The version that has been appropriately designed is new and better. Instead of being recalled, the first design wasn’t. It doesn’t take an engineer to comprehend this, but because I am one, I am perfectly aware of the “whole picture” of the recall and why the crankshaft sensor repairs weren’t included. I’m asking Nissan to pay the full price for the camshaft and crankshaft sensors as well as the necessary labor. When the initial recall problem occurred and my car switched off on the highway, I was put in danger. That encounter was horrible enough. Nissan wants $400 from me in addition to that to fix the malfunctioning sensor that was a major factor in why this happened in the first place.
Crankshaft Position Sensor Issue
A malfunctioning crankshaft position sensor is one of the most frequent causes of the problem when the car switches off while being driven. The crankshaft position sensor’s job is to keep track of all the moving parts of the engine, including the crankshaft, valves, and pistons. It keeps track of the crankshaft’s speed and position to help determine when fuel injection and ignition should take place.
To put it simply, this system is necessary for your engine to operate at its best. A cylinder will misfire if the crankshaft position sensor fails to give the Engine Control Unit the accurate information about where the pistons are located in the engine.
The check engine light may illuminate if the crankshaft position sensor is malfunctioning. The tachometer not functioning properly is another indication that the crankshaft position sensor is broken. The gauge on your dashboard that displays your car’s RPMs is called a tachometer and is normally placed next to your speedometer. Each time you crank your engine, the tachometer usually rises. The tachometer will remain in place once the desired speed is reached.
The ECU will then communicate information to the tachometer after obtaining data regarding engine speed from the crankshaft position sensor. Therefore, a malfunctioning crankshaft position sensor will provide inaccurate and irregular data to the ECU, which is subsequently relayed and results in the tachometer functioning erratically or intermittently.
Other typical signs of a malfunctioning crankshaft position sensor include decreased fuel economy, rough running, misfiring, and full engine failure while driving.
Using an OBD scanner to retrieve the error codes from the ECU is one approach to determine if your crankshaft position sensor is malfunctioning. Your crankshaft position sensor isn’t working properly if you see diagnostic trouble codes P0335 through P0338. Although it might not be possible to identify the specific problem, an OBD scanner is still a great tool for identifying the root causes.
Car Turns Off While Driving: The Reasons Why
Crankshaft position sensors that are malfunctioning or fuel system problems are the most frequent causes of vehicle shut-offs while in motion. It can also occur as a result of a faulty alternator, ignition switch, empty gasoline tank, or problems with the car’s engine sensors.
