I am looking for a little help.New Info!
I have owned my 1972 Spitfire since new. The past year it has run OK but after warming up, stalls at stops. It always restarts but stalls again.

Ignition parts have been replaced but has not helped.
Yesterday we drove to Pueblo, Colorado where it is 95+ degrees. The Spitfire stalled and would not restart!
Fuel pump is probably 20 years old. Could it be the fuel pump?
We pushed the car into a service garage and left it. THe mechanic suspects vaporizing of the fuel and a weak pump.

Latest. We replaced the fuel pump. Runs great on hwy.burt suddenly looses power for 10 seconds then refires. What about rebuilding the carb? Ideas?? Thanks.     David Horwitz captkleen@aol.com

I'd suspect vapor lock, especially at 95+ degrees.  The fuel pump should be an easy test with a pressure gauge.  There is an interesting thread at http://www.6-pack.org/modules.php?name=Forums&file=viewtopic&p=17014 on the topic, specific to TR6's, but certainly the idea is the same.  Someone writes of insulating the fuel line.  Hopefully, others with more knowledge than me will likely speak up here.

Since you replaced the fuel pump sounds like the problem has changed a little.  I had the same problem last year when I changed the fuel pump on my 78 spit.  There are two different styles for my year.  One with a curve arm and one wihtout.  I installed the wrong one and it did exactly what you are saying, it would lose power for about 10 seconds on the highway then it would recover.  The mechanic told me volume was to low to keep up under extreme conditions.  It would work most of the time then all of a sudden starve its self.  DO not know if that is what you are going through.  If it is try another fuel pump.  Good luck.
