I'm pretty sure you must mean in parallel with the Temp Gauge, not in
line with it!

Your problem is, you are driving much too hard. Or else you need to
buy gas in larger incements. Spitfire or no, buying gas by the pint
won't get you very far.

Well, obviously you stopped to buy gas sometime during that day,
didn't you?
Seriously though, it sounds like a carburettor problem, which is to
say, it is electrical. I don't recall with confidence whether the
fule guage (note the proper spellings) reads full with lower
resistance or higher resistance, so I can't say whether an empty
reading means a short or an open circuit. But IIRC correctly it
means an open circuit. You have a bad connection somewhere, anywhere
from the voltage source all the way back to the sender. The apparent
correlation to driving time might be due to drying up water than had
condensed into a connector diring the night. That may be a clue as
to where to look.
