ONAN MARQUIS 5500

Yesterday, while exercising my Onan 5500, turned both roof a/c's on nothing else. Genset ran with both a/c's on for about an hour then aburptly shut off and would not start again. Went out this AM and started fine? What is going on?

So the 6 volt batteries didn’t throw any codes? Insightful. Such things are the basics of RV electricity....12 volt and 110 volt. lol
