Tuga,

Sounds like you were putting a major load on the gennie with all four AC's running, people in and out of the coach, and no cooling space. The temp and humidity you quoted puts a big load on the AC units.

The gennie slowly stumbling and stopping sounds like a fuel problem. If the overtemp sensor kicks in, it shuts the fuel solenoid off, and the engine will stop quickly.

I would replace both fuel filters as my first order of business.
