coughing yellow truck

[melloyello]

Where to start....sigh well every night on my way home from work my truck seems to sputter and cough and damn near die...The truck is warmed up and been driving great I've replaced the fuel filter and pump and had my carb rebuilt yet it still seems to fail ....I'm at my wits end here the engine runs like at top after I shut her down for a minute on the side of the road....anyone see what I forgot to check or fix? thanks for any replies
