I was driving on a freeway when suddenly my truck lost all power. I managed to coast to a safe spot to park. I immediately opened hood and started troubleshooting. Left key on so I'd know if power came back on. After about 10 minutes of moving wires gently I found the issue. A power wire plug connected to cab. I wiggled it and everything worked again. Messed up again and again, that day. Vehicle was still warrantied, but shops didn't have time to get it in. Finally I found a temporary solution. If I hold wire sideways after cutting zip ties it wouldn't mess up again. Shop said they must replace entire wire. Totally a safety issue. Could have resulted in bad situations if it happened at the wrong time.
