Sputtering popping no power question

My 1992 f150 with 302 and aod tranny has been having some problems. The idle fluctuates sometimes but eventually smooths out. The main problem is when its been sitting outside all day in the heat, you start it up, sounds good till you try to give it some gas and it starts popping and sputtering and has no power. The problem is worse the more gas you try to give it and sometimes you can nurse it along by barely pushing on the pedal until it gets up enough speed (usually around 55) and it will keep going but slow down or come to a stop and it starts messing up. After a while it will leave you sitting on the side of the road, let it sit for a while and you are good to go for a short time. I never have the problem when the air temp is low.

Within the last year it has new...
IAC
MAP sensor
Egr Valve and sensor
air temp sensor

Any help would be appreciated thanks

Not saying this is your problem.. hell I dont even know if it has one.. .but have you checked the tps? (throttle position sensor) My mustang used to do that and I had a bad tps.
