There are several reasons why a car may suddenly stall and fail to start: 1. Fuel system malfunction: Using low-grade gasoline with high gum content may clog the fuel lines, causing insufficient fuel supply to the engine and resulting in stalling. It is recommended to clean the engine's fuel lines, injectors, and other components. Alternatively, the fuel pump may be faulty and require replacement. 2. Engine ECU failure: If the ECU malfunctions, it cannot send correct instructions to the engine, leading to stalling. 3. Power supply system failure: A dead battery or faulty alternator can cause the engine to stall. It is advisable to first check the battery's charge level before determining the appropriate solution.
