Generator keeps stopping

I dry camp a lot so I depend on my generator. I bought my current used moho (2014) last August. In September I dry camped for 11 days and my generator would run and then start surging then stop. It did not matter what I was running on it. The first time it stopped I was able to restart right away and it ran for about another hour. Then quit again and would not restart. The next day it ran some more. I was able to keep my batteries up enough to run the fridge. When I got it home and took it to my repair people (an onan dealer) they ran it for hours and hours and it ran fine. They said they could not fix what wasn't broken. So this year I just returned from 9 days dry camping. Yep. Same problem. This time I did notice an error code on the dash. It was Engine Stopped Fault. Any ideas? It has been suggested it may be the fuel pump?

    Oops. Sorry. It is gas. Onan. Either 5000 or 5500. I am not mechanically inclined. When they say fuel pump is that in the generator or the coach engine? I always make sure the fuel tank is full when I dry camp.

    Please tell us what generator you have-- we don't know if it is diesel, gasoline or LP.

    Possibly the fuel pump. The electric pumps will fail when they get hot from running then start working again when they cool off. Eventually it won't work at all. Also make sure you have enough fuel in your tank. Most are designed to cut off when the rig's gas tank gets down to about 1/4 tank. Mine cuts off at 1/2 tank for some reason.
