I just came back form my trip and here is my proplem. Before I left the generator work perfect. Drove 600 miles and parked in the finest hotel that I can find parking lot

and fired up the old generator for about 3 hrs. All was well. Drove 250 more and park at the camp site. We lost the power at the site that night so I when to start the generator and no luck no start. So the next day I check every thing out an this is what I found. When I hit the "start" button I think from what I can tell there is a fuel pump that runs while I hold the start button on. Then I took a test light to the stud on the starter and ther was no power there. I check 2 fuses and the look good. Any ideas???
PS I have a 7.0 Onan generator in a 95 MH LY
