What would cause the gauges to quit working periodilly, they may quit for a few swconds and then come back on. Speedo, tach, gas, and temp. It has been dry ever since I have owned the car, today is the first time i have driven the car in rain since I owned it. Gauges quit

Please any suggestions

 

it could be a loose connection in back of the inst cluster, or a fuse getting ready to fail, or voltage regulator that feeds the inst cluster
