The first few time the car stopped, I reached back and opened the fuel cap.
I could not hear any "whooshing".

I have a ceramic-coated 4-2-1 header from Spitbits with no thermal
separation near the carb with a new Pertronix electronic ignition module and
coil.

I'll try the cheapest fix (new fuel filters) and work my way upwards in
price. I suspect that there is blockage in the fuel system to the point that
when I'm below a third of a tank, there isn't enough "head" to get the fuel
all the way to the pump.  I neglected to mention that this started a couple
of years ago after the car just sat for a 5 month rebuild of the front
suspension.  I suspect now that the gas tank got rusty from the non-use of
the car, and has been getting more and rustier since then.

The next step would be to coat the tank with the kit from Eastwood.  After
that, a new tank from Spitbits.


Thanks, all.  Have a great British Car Week!

The gas tank vent that runs to the charcoal canisters might be blocked.  If 
so, as the
fuel is pumped out, it creates a partial vacuum in the tank which the fuel 
pump is eventually
unable to overcome.  This is easily tested by opening your gas cap when the 
car dies.
If you have a WHOOSH! of inrushing air, that's your problem.

Best!

Greg
