I would start with your transfer switch. It sounds like you are loosing one leg of power from the 50 amp output, therefore one leg is not powering your converter and other appliances, plugs, etc that are on that leg. The legs are usually labeled as L1 and L2.
Open up the cover of the transfer switch and first check for anything that may look burnt, or any loose connections with all power disconnected. Then connect to power and check for power on L1, then L2 on the output side while on shore power. Then switch to the generator and do the same check. I would bet that the contactors are losing one leg of power when on shore power only.
The refrigerator and furnace require 12 volts from your batteries to operate the circuit boards so that is one reason for them to not work if your batteries are dead.
