Might be time to find somewhere that can run a full diagnostic on the truck. Did it once to mine and they told me it was the plugs. A lot of places offer it for free in the hopes that you'll have them fix it but it's not a binding thing. Take it in then do the repairs yourself. If you feel bad give them like $20 that's what I did.

Recently on my 2006 FX4 5.4L, had the same type of issue. Lacking power generally, and CEL would come on under heavy acceleration. Set a #3 cyl misfire, and if I pushed it #1 misfire. Looking at the firing order, 1-3-7...., I became suspicious of the cat on the passenger side. Drilled a small hole in the pass side pipe before the cat, and put a guage in it with a hose to my windsheild(so I could view while driving). At idle seemed OK 1-3psi, higher speeds steping on it, I had a reading of over 18 psi. Put a boroscope in the hole, and the honeycomb had fallen apart piling up. Replaced both cats, and fixed. Lots of power, better fuel economy, just generally runs GREAT. Lots of power.
