94 intrepid cruise controls cuts out occasionally

The cruise on my intrepid will work fine for some time then out of the blue it will just shut off. The light on the dash and everything. When that happens I can hit resume or cruise and the light on the dash will momentarily come on, then it's off again. If I wait five or ten minutes it will work fine once again? Is there some sort of relay that could be weak or something? Any advice would be great.
Thanks
