Gauge failure perhaps. Hard to tell without knowing more.
An easy way to tell is to get one of those inexpensive three-gauge clusters from an auto parts store and hook it up. They come with oil pressure, coolant temp and battery gauges.

Most likely its the sending unit going bad. Possibility of the wire that goes to it as well. It's rarely the gauge itself that goes bad though.

I'll vote for a funky sending unit, but check the wire connector first. Unplug it and spray the metal contact with WD-40 to remove any corrosion inside the connector.
