Why does a car suddenly stall while driving?

[Gerald]

There are generally 5 reasons why a car suddenly stalls while driving: 1. Electrical circuit failure. This is caused by low-voltage power interruption during driving, leading to stalling. At this time, it is necessary to check the ignition and starter switch, as well as the fuse box. 2. Low-voltage line short circuit causing stalling, which results in intermittent stalling. In this case, the low-voltage lines need to be checked. 3. Component failure. 4. Fuel system failure. This includes damage to the fuel pump, rupture of the fuel line, blockage of the carburetor fuel inlet, or insufficient fuel in the tank. 5. Ignition system failure, where the engine's overheat anti-explosion system malfunctions.
