Sounds like a wiring issue.

This system works off of resistance. The sender is basically a resistor that varies the power to the gauge, causing it to go up or down as necessary. But resistance in wiring can vary due to intermittently open circuits and improper grounds, for example.

Checking the wiring between the sender and the instrument cluster is the best next move.
