94' CHEVY K1500 Z71 350?

Runs great for about 25-30 minutes but once it get warmed up step on the gas and wants to kill. Almost like its not getting gas. Its not overheating. Once it gets cooled down again it does same s***. Grrrr

If your wires, cap, plugs, rotor are good, I'd say to replace the MAP sensor. It is behind the throttle body on the passenger side. Runs about $40 at auto zone.

You might also want to check your vacuum lines as well to make sure none are cracked.
