Car lost all electrical while driving

Had power at battery and relay. Power stopped at fusible link. Disconnected link and cleaned both ends the best I could and reattached. Lights came on. Made sure car was in neutral and turned the key and she fired right up. Success for now. Thanks for all the help and ideas.

I am having a similar issue which just started popping up. The car is running great. About 2 months ago I took it on a long trip, and it ran perfect the wHole way. Got to my destination , got up the next morning to cruise, went to start it and nothing - no power to anything. Had a similar thing during build and it turned out to be loose ignition wire to switch, so figuring it was the same thing I pushed it into switch and everything came back to life (I have complete new wiring - Ron Francis Access24/7).

Fast forward to yesterday - I’m about 1800 miles later, interstate driving (but only for about 20 minutes) no problems. But it is really hot out. Pull over to gas up, go to start up - click and then nothing. Fiddle around with the back of the ignition switch like before - nothing. Under the hood the battery cables look good, engine ground looks good, coil connections look good. Alternator (new last year) - i wiggled the main power connection (thick red cable) at the alternator and also at other end (where it connects to starter). Get back in and it fires right up. Huh? Don’t know exactly what happened, but what the hell i drove home and all seems well. About 3 hours later went out to start up again, got power to everything when I turned the switch, a click and then nothing. Repeated the same process as before, and eventually everything came back to life, she fired up and drove great again. I’m planning on attacking this problem in the next few days and here’s my plan: (1) check wire connections to starter (heat related issue there?); (2) replace voltage regulator. After that, I’m thinking replace starter (it is original with about 120K on it now). I will let you know how it goes and hopefully my experience/fix attempts will help you with yours.

Sorry to be so wordy but I thought the detail might help.
