Why does instrument cluster fail to work properly at all times? on 1997 Mercedes-Benz E320

When vehicle is cool and initially started, all instruments on cluster work fine. After driving a few miles, shutting vehicle off and restarting, none of them work. No gas guage, speedometer, temp gauge, nothing. next day or hours laterm they work fine again on initial start-up.
