Yes fluid level is good. Pump just kept starting and stopping. Then just stopped all together. After a rest, it started working normally.
It just amazed me that the problem only happened at the one campground on the way out and again on the return trip. 5000 mile round trip. I guess just a strange coincidence.
As ScottG pointed out it acted like a thermal overload breaker,or a sticking solenoid . Still not sure if the system even has a thermal overload let alone where it could be located. I also will check the supply wires and ground for tightness.
Thanks again guys.
