New to us 2010 Winnebago Tour 42AD

Good evening we recently purchased a 2010 Winnebago tour 42AD model and we took it out this past weekend and found that after about 7 to 8 hours the generator which is an Onan, would all of a sudden sound like it was going to stall, and then it would ramp back up again. And then it would do it again and then it might be fine for two or three hours, and then all of a sudden sound like it was losing power again kind of like it was having a power surge. Any idea what could be causing that and how you can fix it, thank you any help would be greatly appreciated.

Greetings Laplante,
This is a really wild guess, but could a connection be coming loose near the generator where the vibration is the highest? I believe a loss of electrical load could cause a brief over-voltage shut-down, and when the engine's vibration is reduced, the connection drops-back on???
Do you have any error codes?
