soxbrat,
What brand is your generator? Is it an Onan 5500 or 7000 by any chance? I know that many of these are very sensitive to oil level, and in my case, oil weight. Mine used to shut down frequently while traveling on the road in hot (over 90 degree) temps. I was using the multi-viscosity oil Onan recommended for the temperature range (5W30...I think, but would have to check.). I discovered that the oil level would drop a bit while traveling, so then I got into the habit of checking/topping off the oil level on the generator before and after every trip. That helped, but it would still, on occasion, die...especially after going over a pretty severe bump or road heave.
I switched to straight 30 weight oil (also recommended by Onan) and haven't had the problem since. I know the multi-vis oil was supposed to be as thick as 30W in the heat, but I don't think it was, and thus sloshed around a lot more. That's the only thing I can think of.
I don't know if your issue is related to the oil, but I do know that the oil level shut-off switch on these Onans can be very touchy.
Good Luck,
