Bucking & Shuttering

This may have been covered before, but I couldn't find a thread....I was just getting up to speed on the highway when my truck started bucking and shuttering. It seemed to last about 7-10 seconds. It felt like I was going over extremely rough road, which wasn't the case. I began to let off the pedal and switched lanes. No codes thrown nor anything odd on the gauges that I noticed anyway. It seemed to go back to normal afterwards. I'm taking it in for the nox sensor, which I hadn't done yet. I've got about 15,000 on it and it was unloaded at the time. I get my diesel at the same Valero I always do and use PM22 religiously. Any ideas?

Forgot to mention that I drained DFCM after it occurred, a little more than normal, and saw no water. I'm pretty good about doing that monthly..never seen anything. Anyway...let ya know what happens next week, it goes in Monday a.m.

I had some episodes like that a while back and Ford replaced the Crank Shaft Position sensor (at around 15K miles). No such problems since.

do you think this is engine or suspension related?

I don't think it was suspension related. Caught me by total surprise....first thought was engine..just because of other stories if heard.

Mine does it occasionally and I'm sure it's the engine. It normally happens around 50mph when in 6th. I first notice the hopping, then if I try to accelerate it clatters and gets worse. If I let up for a few seconds it stops and starts running normal again. Overall it only lasts for 20 seconds or so. I'm guessing it's the regen cycle.
