1993 Dodge Caravan Instrument panel Caution/warning lights & gauges

Sirs, I have been having problem with my vehicle’s instrumentation panel. This vehicle has a 3.3L V-6. first start of the motor everything seems just fine but after the motor heats up for about 5 to 10 minutes, the “Check all Gauges” light comes on along with all the warning lights on the instrument panel and RPM, fuel, temp, oil press. gauges registers zero, while the motor still runs smoothly at idle and response good when pressing down on the gas pedal. What can I check for and do to correct the problem with my vehicle? Any information that you could provide is greatly appreciated. Thanks for your time. V/R, /s/Ray
