This is certainly a strange malady! Let me guess: Do you have a Holley
carburetor? Thought so.
To start gathering data, next time it dies like this, before you do anything
else, take off the air cleaner and watch the accelerator pump nozzle while
you operate the accelerator linkage. See if there is a stream of gas from
the nozzles. If not, your float needle valve is sticking shut for some
reason, and when you crank the engine slowly, the fuel pump isn't popping it
open. So it is possible that your needle valve is worn.
If there is a healthy squirt from the accelerator pump nozzles, then I
suspect your car is flooding out when it dies. You don't mention clouds of
black smoke when you restart, but this would be another indication of
flooding. If this is the case, you still have a float problem, probably
the float level is set too high. Even more likely, if and only if it is a
Holley, is an internal leak in the carburetor - probably at the power valve.
