Thanks for the replies. My Carburetor has been rebuilt about 3-4 years ago but truck sat around for about a year. I was thinking about buying a new one along with a throttle body spacer. After some research about vapor lock I found this.......

Your symptoms are those of a leaking carburetor, flooding the intake manifold with gas. The fact that the accelerator pump chamber still has gas in it doesn't mean that the main bowl is still full. My guess is that there is leakage inside the carburetor, drowning the engine until you crank through enough air to blow it clear so the mixture can get back to normal. To prove this, run the car until it is thoroughly warm, then shut it down and quickly remove the carburetor from the intake manifold without tipping if over, so that it does not spill any gas, then set it on a clean dry paper towel on your workbench. Come back in an hour or so, I'm betting you will see and smell gas on the towel.

Another way to prove this to yourself is to let the car sit for an hour or so after you turn it off, then open the hood, lift off the air cleaner, and smell down into the carburetor - I'm betting you will smell gas down there, and maybe even see liquid gas on the throttle blades.

Carburetors which have been through the rebuilding process often develop this problem, as the cleaning chemicals remove the sealing coating from the porous aluminum and pot metal parts. The only cure is to replace the carburetor with a new (NOT REBUILT!) carburetor.
