I have a Coachmen 2006 Ramp and Camp that has a 4000W Guardian Gas Generator.  When the temp in Arizona reaches 100F this generator will cut itself off after about 10 minutes of running.
The Generator service guys said it is the Oil Temp sensor.  During the summer, most days and even some night in Arizona is 100F plus.  Any ideas on how to get this thing to run in this heat?
 
Have you ever actually checked the oil temp ( with an infrared temp reader ) . If it is getting above the "safety" zone temp for the engine , well , the only thing you can try is a higher viscosity oil  , say like 50 weight ( not multi weight - straight weight and NOT cheap oil either - they break down WAY too fast . HIGH engine temperatures is what kills oil FAST )
Also , make sure the genny is getting plenty of air circulation all around it  ----if possible
 
tomhilton, did you ever figure out what the problem was with your generator?
 
I tried 50 weight oil which let it run a little longer.  But the real fix was to sell the RV.
