My Temp Gauge is Posessed !!!!

So I'm driving last night and all of a sudden my coolant temp guage dies , and the DIC reads Engine Hot/AC off (somthing like that) - The gauge is reading zero , all the way to the left , so I figure its BS .
I pull over , cars not hot ,plenty of coolant in the tank, engine oil temps fine. So I drove home and the next morning took it to my Vette shop - 40 minute drive and when I get one block away from the shop the friggin thing starts working perfect ( SON OF A BITCH !!! ) so I shoot the crap with them for a few and drive to work .....
TONIGHT IT HAPPENED AGAIN !! - And I know the same crap is gonna happen again , I just know it .....
Any ideas ??? Where does the temp gauge read from , is it somthing I can check for a loose connection ?

Couple years back I put a mezziere elec. pump on a C6Z and could not use the thermo they sent (would not fit) and could not use the stocker and guess what? And to think....I thought it was useless info in my head, I got a lot
