What are the reasons for a sudden engine stall while driving the Bestune T77?

[RowanLee]

Reasons for a sudden engine stall while driving include fuel system failure, electrical circuit failure, ignition component failure, etc. Fuel system failure: Fuel pipe rupture, fuel pump failure, fuel depletion, or fuel inlet blockage can cause the engine to stall. Electrical circuit failure: Short circuits in low-voltage lines leading to power interruption, check for faults in the ignition switch and starter, as well as blown fuses in the fuse box. Ignition component failure: Faults in components such as the ignition coil, ignition module, or spark plugs may cause the engine to start, stall after a while, start again, and then stall once more. Engine belt misalignment or breakage: Belts can age and loosen over time, leading to breakage or misalignment, which can cause the engine to stall. Lack of driving skill: Automatic transmission vehicles generally do not experience stalling, while manual transmission models require proper clutch and throttle coordination. Sometimes, if the car's speed drops and the driver does not downshift, staying in a high gear instead of shifting to a lower gear, the car may stall.
