In cases like this, every little detail counts, so that doesn't bother me one bit! I've been running this through my mind all day, and have one possiblity for you to consider. One of my fellow experts has been following this thread, and has a very good idea to, so I'm going to throw that out there. His is an easy one to try, and probably spot on (he's a smart fellow!)..
Swap fuels out. Try a few tanks of a different brand. If your running premium, switch to mid (89) or even regular (that's what I run in mine). High octane fuels are good from a octane perspective, but bad from a cold start perspective. They are less volatile, and can cause driveability on cold starts. There is actually a Dodge TSB about high octane fuel causing driveability issues in Dodge vehicles. I think that this is the easiest thing to try, and a heck of a good place to start!
My next suggestion is a possible failing O2 sensor heater. If it's heating up slowly, the O2 won't function when the truck goes into closed loop (which doesn't take long) and will cause the truck to run rough, lack power, etc.. until the oxygen sensor
heats up enough to function properly. Lot's of folks describe it as sounding like the truck is running underwater.. Very common on the older trucks, not so common on the newer trucks. Easily picked up on a cold start with a scan tool, if the tech knows what he's looking for. I'm not sure how you could diagnose this yourself, short of changing both upstream 02 sensors. I only mention it becaues it sounds very much like your problem to me.
I think the best way to fix this truck, is to have the co-pilot installed by your dealer. It's a small box that records all the sensor readings when the problem is occuring. You just push a button, and it will record all the sensor readings for 60 seconds or so. Works great, makes it easy to spot any type of sensor problem. Probably going to be relatively expensive. They will likely charge you to set it up + install on the truck, and charge you again to remove / download / diagnose the issue. I think this is the way to fix your truck though. 2 or 3 good recordings would go a long, long way towards resolving this problem.
I realize this is a long way from a definative answer. This is a tough one, and this is the best I can do to help you out from here. Please don't feel obligated to accept, but I have to post this as an answer.
Sorry I couldn't be more helpfull.
