I take it you don't want to try and service yourself?
You may want to try a little trouble shooting, so that when you bring it in, you will save a bit of money, with them not having to do that.
1. At the outside of your RV, (and I'm assuming you've got an Onan genset), you will see that there is a start switch on the generator. This "rocker" switch will prime the engine, if you hold the "OFF" side in for a few seconds.
2. Listen to the pump prime....a clicking sound. Then start the engine, and run it until it cuts off again, then quickly try to PRIME again. If you don't hear any pump noise, there is a really good chance that your fuel pump has worn out. What it is doing, is to run until it overheats, then cuts off....which cuts off the engine. In a few minutes, it's cooled down/reset, and you can start again, so it's important to check the pump as soon as the engine cuts off.
3. When was the fuel filter last changed? And how often has this unit been run? If you don't run and exercise it at least monthly, it is possible that the fuel has started varnishing in the filter or carburator, which will effect operation. You could disconnect the fuel pick-up hose under the RV, and have it suck out of a smaller container, with a mixture of gasoline and SEAFOAM fuel cleaner. Let this run for about a half-hour or so, and you may not need to take the unit in for Service.

I got the RV with only 28 hours on the generator back in November. It currently has around 70. So I have been using it fairly frequently. But recently it has run poorly. Surging and now won't stay running. Tried seafoam in the gas tank and that seemed to help smooth it out a bit, but when I ran it again this weekend it would die.
I don't mind doing self maintenance but I don't want to screw something up even worse. I will check the fuel pump this weekend and go from there.
