Electrical problem with 2014 Heritage Glenn

Update. Today the power went off again and I went straight to the campers panel box. I took the cover off and tested the wires going to the main breaker and nothing, wiggled everything and power never flashed on or anything. Went to the plug on the outside of the camper and tested the power cord and had power there but noticed that one of the holes on the end of the power cord had melted a little. My guess is it happened the last time the power went off because I remember the power bumping on then right back off 3 times over 20 mins until it finally stayed on, but I really don't know. Anybody have any guesses? I would think a loose connection arcing could cause this but the connection between the power cord and plug on the side of the camper feels tight.
The power did come back on about 10 mins or so after coming back inside but I'm a little worried after seeing the burnt end of the plug
