Having to park my bus without electrical hookups while storing it. Been depending on Generator Auto Start to keep batteries charged and running one or 2 ACs to prevent delamination of my cabinets. Generator will crank and run for about 10 minutes with 1 or 2 ACs running but then starts heating up and will shut down automatically. I have checked coolant levels in radiator and reserve tank, checked air filter, replaced fuel filter and none of that helps. Would appreciate any advice on a possible solution. I am in a semi remote area of Montana without service guys so I'm trying to do it on my on but temps in the low 90s are making me anxious. Generator has only about 1400 hours and a "service" was done a few months ago. Appreciate any help. Thank you, Mike shaw
