Cruising up I-75 today so ran the gen. and house ac. Gen. ran for a while (about an hour)then decided to shut off. Any ideas??? (Plenty of fuel and only the front ac on)

Dig out your generator manual and read the section on trouble codes. It will tell you how to retrieve the last code generated when it it shutdown abnormaly. The code will tell you why it shutdown.

Thanks heybc, will check it out when we stop tomorrow. Probably won't need it until I get home.

We have had 3 unexplained "on the road" shutdowns of our Onan (05 DSDP) too. We get fault code "3", then subcode "36", which apparently indicates that the unit is starving for fuel or air is being drawn into the fuel system - have not figured it out yet and since it is an intermittent problem it will be hard to find the problem

If you have plenty of fuel, remembering that sometimes are fuel guages are less than accurate to actual level in the tank, (my low fuel light comes on at about 35 gallons of fuel remaining for 100 gallon tank). I would check/change your generator fuel filter, especially on coaches that have shifted from low sulfur diesel to ultra low sulfur diesel. May be a victim of tank wall sludge phenomenon that is being experience by some.

Or your fuel pickup is too high. We had a coach that pickup was at 1/3, real pain during the power outage of the Hurricanes. Haven't verified current coach but if more than 1/10 will change.
