Default Need generator advice.......

I have a 2003 Pleasureway excel with an Oman 2k generator. Now when dry camping and trying to run my A/C with the generator, it runs for about an hour then shuts down. A had a generator service done 6 months back, but the generator consistently stalls out. The AC runs fine when on campground 120 volt. And I have plenty of gas in the camper gas tank. Any idea as to what the problem might be?thanks for any tips!

Is it possible that you are turning too many other electrical devices at the same time the AC is on?

The AC takes a lot of current, especially when starting up, so maybe after it has been running a while, if you turns something else on such as a kettle, hair dryer, etc., then the next time the AC starts up, it might kick out the the breaker on the Onan (It has its own breaker right down on the unit.

Although if that were to happen, I would have that the Onan engine would keep running but just not put out any power - not sure about that though! Otherwise it could be a problem totally unrelated to the electrical load. carb? ignition? propane pressure (if running on propane) gennie oil level?

IIRC, some members have reported this symptom and resolved it by replacing the fuel pump.

I wrecked my fuel pump by adding additives in my tank. Stopped using them, and no problems since. And remember, the more you run it, the better it runs. At least 2 hours per month, under 50% load is recommended by Onan.

What additives were you using? There has been enough Seafoam and other cleaner/preservative additives used over the years in these Onans to float the Titanic, without issue, from all I have heard.

I was using Techron Injector Cleaner. I'm using nothing now, and running perfect.

How did you determine it was the Cleaner that damaged the fuel pump?

Just an educated guess. The pump actually dissolved from the inside out within 20 hours of use. I use fuel exclusively from Pilot / Flying J. I'm now at 136,000 miles, 150 Generator Hours, and no fuel issues other than this incident.
