ONAN runs, stops, starts again
I was exercising my ONAN 4000 the other day as I do monthly and after about 45 minutes it just shut down. It re-started after a couple of minutes, again after 30-45 minutes before shutting down again....

UPDATE…
I pulled it out of storage far enough to add Sea Foam to the fuel tank and change the gas cap. Checked the air filter and it’s still clean. I used my leaf blower to remove anything that might be blocking airflow. I didn’t see much come out.
Started right up…ran for 20 minutes with load and shut down. Nothing blinking on the trouble code, but the compartment did feel hotter than normal when I opened the compartment door.
I set up a fan to blow directly into the compartment with the trailer access door open and the GenSet cover still in place like the instructions state. Started GenSet ran with load for over an hour and a half with no problem. The compartment was much cooler than with the access door closed.
It’s (maybe) a heat issue so I’m going to try and find out how the air flows through the GenSet.
