DSRaven,
Thank you for all the information. Before the truck wouldn't start out on the driveway it was running about a week or two before. So at this point in time heat soak or boiling fuel would not be a problem. But I did think of picking up one of the carb gaskets like below to prevent any boiling/heat issues in the future.

I thought it might have been an issues with the accelerator pump in the carb as well but I dont think so at this time. After cranking it and cranking it over I actually climbed up under the hood to take a look down the carb. I could smell a hint of fuel and pumped the accelerator pump and I did not see it shoot any fuel into the bowl.
I knew the bowls were empty from it sitting for a week or two but now I'm thinking it might be a weak pump in combination with fuel drain back. I was talking with my father about it and he said he had a simular problem with an old 67 Javelin he had. He said it would run fine if you were on the flats but as soon as you drove up a hill the car would die. He replaced the fuel pump and the problem was resolved.
Like you mentioned DSRaven it could be a stuck valve in the fuel pump possibly keeping it in the open position and allowing fuel drain back. I will give your test a try to see what I will get from the line on the carb with my compressor. How much fuel should I expect to come out the line when doing the test? Its easy enough to remove the line from the carb and do this test.
As I mentioned the edelbrock fuel pump was on the engine when I bought the truck and I'm not sure how old it is or if it was used pump or new when put on the engine. So that could be another culperate in the chain of events. My father suggested to replace the fuel pump and put in a check valve and that should solve the problem.
What are your thoughts?
