Thanks and will look for the code. I did find on another internet site that this same issue is a very common issue with Thor Motorhomes. Thor knows of the issue and is an issue of heat possibly vaporizing the fuel going to the generator. Seems that the heat from engine and roadway is overheating the fuel causing the vaporization which is possibly why after running for a couple of hours, it was not problem and I tried to simulate issue on driveway to never shut down on me. Am told that it is generally while traveling while running generator in the good old Texas heat which we had 99 degree temps this past Friday. Will have to see next time if it does again and look up code but Thor is not doing a lot to correct the issue and either way, mine is a 98 model which they likely wouldn't really care anyway but seems to be an issue with newer versions also.
Maybe no one else has seen evidence of this same issue? Where I saw it was on another Forum and had quite a few had similar issues while driving down the road in 95+ temperatures.
