Update and problem solved:
I couldn't replicate the problem until recently. Previous to that I had verified all connections were clean and good. But on our last trip out it finally happened again. Starting at the batteries and working back I didn't have to go far (Thank you DrewE). It was the self resetting circuit breaker. With lights on and pump running the voltage going into the breaker was normal, but the output side would drop significantly and bingo everything blacked out.
The difference now was the power was out longer whereas previously it rebounded instantly. With every repeated failure the power seemingly stayed out longer. So while the breaker was already failing, it's definitely on it's last legs now. I don't totally understand why the problem couldn't be replicated until now as I thought once mechanical breakers start to go they are basically toast.
I had a spare 30A in-line fuse that I put in place and life is good. I haven't decided if I'll replace the breaker, put a manual resetting one in, or just leave the fuse.
Thank you to everyone for your help and advice!
