My dad has the same problem as well, one time when it had lost all power I touched the ground cable, and as you mentioned it was hot and then power was fine. So we knew it was the ground cable at the battery, to resolve it we replaced the connector to the battery with a new one that was soldered in. It has been working perfectly for a couple months now. And while we were removing the old end, it did seem like the wires were a bit loose and the connector wasn't fully crimped from the factory
