Bad coil is the problem. I had the same problem. I was able to take a laser point thermometer and find one that was 20 degrees hotter than the others. The one that was bad was the driver side front one, it had some corrosion on the screw that holds it down.

More than likely a COP going bad. When you take the truck out of O/D the rpms go up and compensate the low grade misfire. A code reader might show a pending code for the problem cylinder.

get it scanned, if your are showing a mis-fire or pending mis-fire it will tell you where, replace that coil.
