Stopped at battery store and had all house and chassis batteries checked and all batteries are good. When we say hard restart we disconnected both battery types, drained power out of all systems and waited 15 minutes to restart. Other thoughts? Thanks in advance.

As others mentioned, see if you have 12v power After the fuse that's usually installed right on the battery(with all systems shut down, no gen, no wall power, no inverter). It's rare that those blow, but if it does, it could help to explain what you are seeing. It would also help to explain that you have might house power with the Gen running or shore power. I can't remember how my system is wired right off the top of my head, but I would check that first.

I would also start checking grounds and the big kill switches.
