Furthermore, why would a car engine suddenly stop? 1) Engine Overheating The most common reason for an engine to stop is that it is overheated. As the internal combustion chamber burns air and fuel to create heat energy, it then becomes mechanical energy which causes the vehicle's parts and components to operate. This will result in the engine shutting down suddenly.
Also, what would cause a car to die while idling?
The problem occurs when the engine is running at low speeds. A pause in the flow of fuel can kill the engine. Defective fuel injectors and low pressure fuel can also cause a vehicle to stall when it is running at low speeds or when it comes to a stop.
Can low transmission fluid cause stalling?
• When your transmission doesn't have enough fluid, you may experience it stalling at red lights or stop signs. Though it should start right back up, taking your car to an auto shop for repair is key as your transmission lines may be leaking and may need to be replaced.

Engines usually stop suddenly only if they suffer from a lack of fuel or sparks . A slower, spluttering halt, on the other hand, probably indicates fuel problems - ignition faults that cause similar poor running are unlikely to stop the engine in the short term.What causes sudden engine failure?
The most common reason detonation occurs is the failure of the exhaust gas recirculation (EGR) system. This system is what ensures a proper air/fuel mixture so the engine will properly operate. It may also be caused by using incorrect spark plugs, bad ignition timing, the use of low octane fuel or running a hot engine.What happens when a car engine fails?
