Default 90 TPI Dies

39 Chevy street rod with 90 Vette TPI, 32,000 miles. Last six months engine has quit several times. Starts to miss then just dies. Let it sit about three hours and it restarts, runs fine until next time. Has gone over 200 miles before doing it again. Happened in hot summer first but now it's doing it in 50 degree temps. External fuel pump, replaced 2,000 miles back. Acts like the old vapor lock.

Does your gas cap have a vent?

Gas cap is not vented, but tank is vented.
