Our Onan 5500 just gave it up with 1080 hours on it.
Symptom were would shut down after about 30 minutes but I could restart it after and hour or so. Then it got to be running less time between restarts. Figured it was from being too hot. Not so. Took it to an Cummings/onan service center and they first found the mother board burnt. Replaced board but didn’t fix the problem. Then with new board installed it was determined that it was the actual armature and the part that is around it to make the electricity had grounded out causing the problem. Replaced those and all is good except for my wallet. $2200 roughly
Take a look at the prices for even used RV generators on eBay. At least you know where yours has been and what was done to it. So, you paid about 2 bucks an hour for power whenever you needed it.
