That won't quite run it. Sounds like you're losing your 12 volt supply from the ignition switch.
Could be corroded wires at the switch, could be the switch, could be the connections on the back of the amp gauge.
There is a large wire that comes off the main battery cable terminal on the starter that goes inside the cab and feeds the amp gauge, then everything else starts feeding off the amp gauge. Maybe that main wire is bad.
