'93 4Runner Gauges Don't Work Won't Shift Out Of Park

I have a 1993 4Runner with 107,000 miles. I have had this problem twice. Once while driving, all gauges went dead, heater quit working. I parked the vehicle, checked fuses, and restarted....the problem went away. A few weeks later I parked the vehicle in the morning, went out in the evening and the same problem. Any ideas??

Thanks In Advance

Found the problem. Fuse holder for the "Gauges" Fuse (#15) was not making good contact. A little adjustment and we're A-O.K.
