First thing I tried was a new fuel filter....did not help.
After it dies there is "zero" fuel at the carb when I pump it manually...bone dry.
When it dies and I try to restart it does not try to fire at all....just cranks.
I know it is fuel related (not spark) because after it dies if I crank it and spray carb cleaner down it's throat it fires right up...and will continue to run for a few miles.

A float sticking from the heat is something I had not considered....thanks patrickt...maybe I will start by pulling the Holley off of my Bronco and see if that solves the problem.
