Likewise, the electromagnetic field will shut down if you leave your generator running too long without plugging it into a device.
Why does my generator keep losing power?
The fuel system might be supplying too much or too little fuel to the mix. As a result, combustion does not occur properly within the engine. Finally, there may be impurities in the fuel (i.e. water in the fuel tanks) which causes the fuel not to burn.
