What is sudden engine stalling while driving?

[VanReagan]

Here are possible reasons for sudden engine stalling while driving: 1. Electrical circuit failure. This may occur due to low-voltage power interruption during driving, causing stalling. In this case, focus on checking the ignition system, starter switch, and fuse box. 2. Electrical component failure. Common issues involve the ignition coil, capacitor, or electronic ignition module. The car may start initially but stall after a while, then restart and stall again. 3. Fuel system failure. Possible causes include a damaged fuel pump, ruptured fuel line, clogged carburetor inlet, or empty fuel tank. The car might restart but with difficulty. 4. Sensor failure. Malfunctions in the throttle position sensor, air flow sensor, intake pressure sensor, crankshaft position sensor, or camshaft position sensor can lead to stalling. 5. Other failures. Serious issues like engine timing system disorder, incorrect timing calibration, or valve collision may prevent the engine from starting, requiring roadside assistance. 6. Use of substandard fuel. Automatic transmission vehicles generally don't stall easily. When they do, the primary cause is usually low-quality (below-standard) fuel leading to engine carbon buildup and stalling.
