I have a '06 Monarch with a Onan 5500 air cooled and had a problem similar to yours.The generator would just suddenly stop running when a/c units were on.1st time I was in 100 degree weather so thought just to hot , happened again in warm wheather but would start after cooling about 15 min.but would run for only10 mins. At home in drive way started checking things out serviced gen. Problem continued, took to a repair shop and after a few hours checking things out and calling Onan they found that the gens fuel pump was getting real hot and could actually burn you if touch. Replace fuel pump and have had no problem for over a year.
Is that fuel pump visible from the opening so I could I shoot it with an IR gun?
