When I got this error on a different model Onan, I found a separate fuel filter between the generator and fuel tank that had never been changed and was stopped up. The generator would run for some period of time then stop with error 32. If I waited a few minutes it would start again for a while then stop. Replaced the filter and it now works fine.
My wife and I would travel full time, but we have to sleep occasionally.
