Chevrolet Le Chi 0.8 emergency throttle flameout

This problem has been encountered before. First, check whether the spark plug is filled with oil after the flameout. Second, check the engine computer board for water ingress, pin angle breakdown or oil ingress corrosion. I have repaired a car before, just like your phenomenon. It is the corrosion of the water inlet ignition output pin of the computer board that leads to poor ignition, which leads to oil filling and the engine cannot be started.
