you may have a short in the light system somewhere. Does you light switch click when it does it. Mine did the same thing when it is doing it I disconnected the four wire plug for the rear, front right, and front left, when it stopped I new it was in the front right corner, sure enough the wire rubbed through on the alum grill shell where it attaches to the headlight bucket.

Might not even be a short. Over time the breaker in the headlight switch will do that no mater what. The proper thing to do is convert to a relay set up for you headlights. Swapping the switch wouldnt hurt either.
