CAT 3196 instrument panel goes dead

[bnr@dur-a-flex.com]

Lately, one of the engine's instrument panels goes into an error mode and all gauges go off when I hit a high RPM (1900 or over).  Engine is running fine and if I come back down in RPM's the gauges come right back on.   Engines are CAT 3196 with the old school analogue gauges.
