I am running a Honda EU3000i generator to power a Coleman 13,500 BTU/hr RV AC unit (8.4 amps for the compressor and 2.9 amps for the fan). The generator will operate for about an hour and then shuts down. Motor and everything just turns off. There is no indication of an overload (no lights, sparks, or hot electrical cords). Even with an overload the motor should continue to run but the generator output shuts off. After sitting for 30 minutes or so I can restart the generator and it works fine again. Ambient temperature is about 105oF I researched the Honda manual and it does not provide any guidance for high temperature operation other than more frequent maintenance. Can anyone provide suggestions on what could be going on?
