The power for both these gauges is provided by a voltage stabilizer that is
mounted on the back side of the speedometer. I would start there. Check the
connections on that. The light green wire runs to the gauges and the dark
green wire comes fromt he fuse that also feeds power to the turn signals,
wipers
and a few other items. If these are not also intermittent then you can
probably rule out the fuse.
As a test you can disconnect the voltage stabilizer and connect the two wires
together. This will cause the gauges to read a bit high but if they become
reliable then a new stabilizer is probably the cure.
Good luck
