A few things come to mind.
First off is the wire mesh ground strap that runs from the rear of the
head to the firewall. These rot and your symptoms can happen.
Second is a bad fuse link wire. If you follow the smaller positive
battery cable to the starter relay where it bolts on, you will find a
few soft fat wires bolted there too. These are about 8" long and have a
fat rubber tube crimp where they join the harness pieces they protect.
One of these could be burnt.
Last that comes to mid is a dead fuse panel. Have you ever had the
clutch or brake master cylinder fail and leak fluid into the cab? If
so, the back side of the fuse panel could be rotted away.
