Pentium B70, what caused the flameout during driving?

Dear students, I would like to ask you to stop the engine suddenly during driving, but if you start it again, it will catch fire immediately and then drive normally! Is this phenomenon related to throttle carbon deposition? Still related to other reasons! Thank you, classmates. I would like to ask you to stop the engine suddenly during driving, but if you start it again, it will catch fire immediately and then drive normally! Is this phenomenon related to throttle carbon deposition? Still related to other reasons! Thank you. The 4S shop also said that the throttle was dirty, so it was cleaned! It is normal at present! Thank you for your answers! I only know that dirty throttle will cause car jitter and unstable idle speed, but I don't know that it will cause sudden flameout! Both flameouts occurred dozens of meters behind the working red light! There are many theories and many results, so it is better to check them directly, so as to save you from wandering out of the city. Thank you for your detailed answers! Thank you, but the 4S store said there was no fault code and there was no way to find the reason. It is also said that the reason for the circuit is not just the flameout, but the whole car is out of power. There is something wrong with the oil circuit, so it can't be started immediately after the flameout! I checked the throttle, it was really dirty and black, so I judged it was the throttle and cleaned it! It's time to clear the throttle. There may be something wrong with the circuit and oil circuit. . The subsequent opening of the dirty throttle is related to the fuel injection quantity. It is reasonable to say that it should not cause the car to suddenly stall. . @20 19
