'91 corvette l98 low volts

Car turns over fires and dies. Ran diagnostics no faults found. Voltage gauge reading 10 volts. Security light off, 13.2 at battery. Happened before, removed cluster cleaned contacts fired and ran OK. This time no luck, read someplace resistor fails, can see it but can read the value. I would be extremely grateful if anyone could help me ou as I'm in the UK and no one has a clue.
