2003 Buick Rendezvous CX 6 Cyl 3.40L
What would cause it to turn off while driving
I'm not sure what the sub model is, I just picked one to ask this question. This has happened twice, once when the engine was cold, I had only drove a few blocks, and once when it was hot, I had been driving for about 20 minutes at 60 mph. Everything shuts off..and I mean everything, but it all comes back on just as fast as it shut off, including the engine without doing anything, and keeps driving like nothing happened.
Several possibilities; faulty / loose battery cables, corroded battery terminal connections, faulty alternator wiring - to list only a few.
