46 may be a low voltage code. That guy ended up needing a new inverter.
I had a voltage problem on mine. Ended up being the output voltage. The generator would run, but as soon as I flipped the breaker on the generator to provide power to the coach, it would shut down and I would get a voltage code. The eventual problem was in my transfer switch; it was fried.
Yours sounds more like input voltage, but then why would it run for a while and then stop? I would think it just wouldn't start in the first place? Unless it has to do with 12V output?
