Default Electrical issues

I have a 77, I drove it the other day about 75 miles with no issues, stopped turned it off and came back a bit later and turned the key and have no power anywhere? The battery is good I have power to the ignition and the fuse panel but no power beyond the firewall and I am stumped?? Any advise?

Default Hi and welcome!

Check that the starter extension harness plug is good it's back near the distributor.
