Hello:
There are generally three reasons why a car suddenly stalls while driving
The first is a circuit fault. This possibility is that the power is cut off due to low level. voltage while driving. Turn off the engine. At this time, you can check the low voltage ignition circuit to see if a fuse is blown, resulting in no high voltage electricity.
The second is a fault in the ignition circuit. oil. The fuel pump is damaged, the fuel line is broken and the fuel tank is empty. But in this case the car can restart. It's just difficult.
