<VV> Elect problem

[Jim Becker]

Do you have a stock wiring system or has somebody "improved" it like with a 
whole car circuit breaker?  That behavior can be caused by a temporarily 
lost connection at your splice or anywhere else along the big red wire from 
the voltage regulator to the first splice in the harness under the dash.  A 
hard ground along the same path and even beyond the under-dash splice could 
do the same, but that would likely cause some heat and/or smoke.

Chevys have a bi-metallic strip in the headlight switch that acts as a
thermal cut-out. Instead of a fuse or a tripping circuit breaker, they
will break the headlamp circuit when it is overloaded, but re-make it
when it cools down. But that doesn't explain why everything else went
off. I would start by checking the headlamp circuit for a short though.
