On the interstate the other night I was a passenger in our car (1992 Mercury Marquis) when the headlights and dashboard lights went out. They stayed off for anywhere between 1 and 30 seconds, and then would go back on for a few seconds. It made for an interesting ride until we could get off the highway.

Does anyone know where I should start looking for the cause of the problem?

Have you looked at the headlight switch. Mine needed replacing because it started to overheat. The dash lights went out as well as the tail lights similarly as you described.
