Default If you can solve this problem you are a genious

This is the scenario:
I start the truck and let it idle for 20 seconds, drive 4 blocks through town then down the highway. I get almost 2 miles down the highway and suddenly the truck looses power, starts to miss and may even try to backfire through the intake. If I accelerate nothing happens until the foot pedal is on the floor then suddenly the truck takes off like a rocket but still running rough. It will do this for about 1 minute then clear up and run great. I sometimes pull over and let it idle out of the problem.

It happens every day, the exact same place on the highway. If I let the truck idle in my driveway after about 3 minutes it will idle rough for about 2 minutes.

If I drive a distance and shut the truck off for a few minutes the whole cycle happens again.

New intake air temp sensor, MAP sensor and had the computer tested by Cardone, they found no issues but flashed and sent back.

I am at wits end with this.
