My happy prince Otto turned off the engine for three or four minutes, and he defeated the master of electronic throttle.

This situation may be that the fuel tank cover is closed too tightly, or there is a problem with the one-way valve between the oil pipe and the carbon tank, and the fuel tank is too full, resulting in slow oil transmission. It is also possible that the ignition components are faulty (mainly the igniter or the stator coil of the magneto), which leads to the flameout of the hot car. You can open the tank cap first and try to run for a while. If the fault disappears, it is an oil supply problem. Check the fuel tank, carburetor and other parts. If this doesn't work, it may be that the ignition component broke down in the hot car. This kind of fault phenomenon is quite regular, and it will turn off after running for a certain distance (or time).
