Causes of car engine Stops while driving
There are many reasons that lead to the car's engine stopping working, and they are:
Ignition system problems
The engine in all cars depends on the ignition system to get the energy needed to run smoothly, and the ignition system contains many components to ensure that the engine works efficiently, such as connections, wires, spark plugs and several other parts, and if one of these parts is damaged, the work of the engine will undoubtedly be affected to an extent that it may stop working because it will not get the energy it needs to continue working.
Crankshaft sensor failure
One of the most common causes of engine stalling is a faulty crankshaft position sensor, as this sensor works to monitor the many moving parts inside the engine including the crankshaft, engine valves and pistons, while tracking the crankshaft speed and position to help facilitate the optimal timing of fuel injection and ignition, when this sensor is damaged, the timing of the engine's work will be disrupted, and it will stop working directly.

Faulty mass airflow sensor
The car engine needs a constant supply of air to complete the combustion process and work without issues, and before the air enters the engine, it mixes with fuel and then the mixture enters the engine in order to ignite it, and this sensor is responsible for giving the car's computer a reading about the amount of air that will enter the engine, and if this sensor is damaged, the reading will be wrong and the car's computer will give a command to raise or lower the amount of air incorrectly, which will affect the engine's work and possibly stop it from working while driving.
Problems with the fuel system
Like the rest of the systems in the car, the fuel system contains many parts and components that ensure the transfer of fuel to the tank and then transfer it to the engine through hoses, connections, electronic and mechanical parts, and these components, especially as the car ages, may be exposed to damage, and since they are responsible for delivering fuel to the engine, any malfunction in them will lead to a malfunction in the amount of fuel reaching the engine and may stop working suddenly.
Alternator failure
The main function of the Alternator is to generate energy to recharge the main battery in the car, in addition to operating the electronic systems in the car, including spark plugs, and if it ages and becomes weak or damaged, the engine will not get the electricity that keeps it running and will stop working whether the car is parked or while driving.

Timing belt failure
The function of the timing belt is to connect the engine pulleys with each other and synchronize the strokes of the valves and pistons by making sure that the camshaft or camshafts are synchronized with the crankshaft rotation, and if the timing belt breaks, the engine component pulleys cannot rotate because they take their power from the engine itself, and this will cause the engine to stop working, and if your car engine has previous issues, the damage may be greater and the engine will fail completely.
Engine issues
The car engine is the part responsible for moving the car, and it contains dozens of internal and external parts that move constantly to ensure its work, and if one of these parts such as the camshaft, crankshaft, valves, piston rings and others fail, the engine will definitely stop working, especially while driving, because the number of its revolutions is higher and the pressure on the parts is greater.
