Thanks, Benzmac. Actually, when this happened, I wasn't getting ANY power at all. The headlights did not work. However, I have (for a long time) had a slight dimming of the headlights when idling or using my turn signal. Had the charging system checked out a few months ago and no problems. Maybe a relay gone bad, or the battery terminal ?
I haven't had any problems since, so I'm hoping that maybe it was just a wire touching the body that shouldn't have been. I'll keep you posted.
