From what you've said it's a mechanical gauge? Mechanical stuff breaks.

Thump it and see if it responds.  I do that in the race car a lot, because I'm too cheap to buy a new gauge just yet.  Usually it's a problem with the capillary tube, but still requires a complete gauge change out.

The mechanical gauges use ether (sure smells like ether, which is wonderful) so if it springs a leak at one of the factory sealed joints, it will leak out and vaporize.  Once its gone the sending unit is dead.  After enough thermal cycles and vibration/fatigue they eventually will fail.
