My automatic urs6 Instrument cluster was working perfectly, the next day the rpm, milage and fuel gauge stopped working. Later all worked fine, but then stopped again. What could cause this?

Might be a loose connection on the voltage regulator which is screwed to the back of the instrument cluster. It's a 3 pin device with the pins plugged into the back of the circuit board, visible on the back of the cluster, remove the screw, unplug it, clean the pins and reassemble.
Looks like this.

If that doesn't fix it you will have to dismantle the cluster and clean the long pins that connect the boards together and make sure their soldering is good and not gone dry/ cracked.
