Thanks for the replies. Temp and fluid levels are all good but I know that’s not what’s causing it. It is hot here though, 108 when we got here the other day. I’ve tested the chassis battery cut off switch and it’s wired in a way that even if you turn it off while the engine is running it will continue to run off the alternator. I’m leaning towards some kind of solenoid or possibly the ignition switch but I don’t know which solenoid it would be. I don’t have any in my front compartment. Just 3 in the engine bay along with a few small silver 30amp breakers.
Here are pictures of both my compartments.
