Sometimes, when I turn on the key the coolant temp LED will flash
as it's supposed to, and the fuel gauge and temperature gauge needles
will start to rise, as they are supposed to do.

Other times, they will act completely dead. Some time during the drive,
they will function and then quit at will.

                        IT'S DRIVING ME NUTS!!!!!!

I put another instrument pod into the vehicle, and the same symptoms
appear, so I am ruling out that the problem is in the gauges themselves.

Could it be the ignition V+ supply is not steadily reaching the
instrument
panel through the multipin connector?

Any one have this problem? Any leads would be appreciated.........
