Intsrument Gauges do not like cold weather??

I'll guess. Failing fuel gauge and/or the limiter. The fuel gauge is already fried and the bad limiter is going to fry the other 2 gauges eventually.
Not to discount others guesses but... fact is lack of ground cannot peg a gauge. Too much ground ( as in lack of resistance to ground ) is what pegs gauges and fries stuff.
