1984 cabby dies warm

[Williep]

I need help. My 84 convertible runs fine in cold weather, starts fine in warm weather but dies about 10 minutes later (above 85 degrees). If I wait 10-15 minutes, it will restart and run for another 5 then lurch a few times and then die again. Fuel pump is new (1 pump model), relay is good, (fuel pump continues to run when it dies). Fuel pump starts off quiet when cold, gradually gets noisier--the last new one I had did the same thing so it can't be the pump. What component on this car is influenced by ambient temperature and assumably causes the pump to increase in noise? Thanks. Bill

What about the in-tank fuel pump. Easy to remove, easy to check, and this was my problem with two different Cabriolet's that I have owned.

Butcher,
Thanks for the push one more time. My VIN did not match what should have been a two pump system, and when I bought the car, it had a full sized spare in the trunk. But logic does not always trump pragmatism. I went out and physically looked at the space and sure enough 5 mile an hour spare smiling back at me from hole . . . New intank pump and once again it flies. I really hate being stupid.
