What causes a car to stall and then restart?
On the other hand, if the car restarts immediately after it stalls, this indicates an electrical problem. Electrical problems are harder to diagnose. Check the fuses and have a diagnostic test done. Other less common causes of a car stalling is a clogged fuel filter and bad catalytic converter.
Why does my Car start but won’t start?
If it cranks but does not start, sometimes a temperature sensor is bad and the computer can’t figure out the proper amount of fuel to inject. Just a little off and the engine won’t start. After a half hour, the engine just happens to get to a good starting temperature.

And–most important of all–does “won’t restart” mean that the starter fails to activate when you turn the key, or does it mean that the starter cranks the engine but the engine does not start and run on its own? Since it’s intermittent and unlikely to be tested while malfunctioning, I would guess ignition module or crank position sensor.
Can a bad fuel pump cause a car to stall?
Unfortunately, there is usually no warning when your fuel pump is dulling. The first time you will notice any problem is after the car stalls. When it stalls out due to a bad fuel pump, you will not be able to restart the car.
