What Causes an Engine to Suddenly Stall?

[Warren]

The reasons for an engine suddenly stalling are: 1. The crankshaft position sensor's own resistance value is abnormal, causing the crankshaft speed signal to disappear after the engine warms up, leading to engine stalling; 2. The fuel pump's resistance changes after prolonged operation, failing to provide normal fuel pressure, resulting in engine stalling; 3. Ignition system failure, where the ignition module overheats and cannot function properly, causing the engine to stall; 4. Abnormal throttle signal voltage leading to engine stalling while driving; 5. Loose wiring causing intermittent engine stalling. The methods to address sudden engine stalling are: 1. Check if the fuel tank has sufficient fuel; 2. Inspect whether the filter is clogged; 3. Check if the battery is supplying power; 4. Examine whether the fuel pump is delivering fuel.
