Try giving the dimmer switch a good shake while the problem is occurring, and switch high to low beam several times. It's quite common for the multifunction switch to fail this way, but it usually happens while you are operating the switch- the lights will go out instead of dimming.

Other than that, the next place to look is the headlight switch. They are cheap enough that you might as well throw a new one at it, and have a good look at the connector for signs of overheating.

By the way, is your headlight wiring stock? You haven't installed a relay kit or anything?

 

thanx torquefan...yeah the wiring and switch is all stock factory..i took the switch out...d/c the wiring to it...sprayed contact cleaner into every crack i could find and tried working it in by pulling the the switch **** out and in....cleaned the connectors...put it all back together and lights turned on first pull...niice...lets hope it stays that way
