I've spoken to a few members and they recommended "0" gauge wire to the battery and frame. I'm currently using 1 gauge. Seems like this would make sense right?

I've never heard of "1" gauge wiring -- typically wire is referred to as "aught" -- so ONE AUGHT -- 1/0 --- or TWO AUGHT -- 2/0.....
1/0 being smaller than 2/0....
1/0 can carry 300 amps for 19 feet --- 2/0 can carry that a bit further.
Are you running 1/0 ?? Or 1 gauge ???
The key is grounds must be as good as the hot side of a circuit. You could conceivably have a "high resistance" connection somewhere in the system - on either the ground or the hot side - and as this connection heats up - it's resistance increases.... until it can't carry the load.
I would "ASSume" there are RELAYS used for switching loads such as this pump and your electric fans etc?????? You could have a bad relay and as it heats up it breaks down.... I've had that issue before.
