Loss of power during acceleration from stop

Loss of power during acceleration from stop
Just wondering if anyone might have any ideas of what could be causing this? I have an '04 F250 with the Powerstroke stock, no mods. When accelerating from a stop light I have a "stumble" i guess you could call it, a loss of power lasting for a few seconds, then the engine seems to pick up. A bit of a puff of black smoke once it picks up and thats it. It idle's fine, starts fine, runs fine at cruising speeds. I don't use it for towing at the moment. The check engine light is not on. Had the fuel filters changed last week and it had an oil change maybe 2 weeks back. Seems to only occur more once the engine heats up as well? Any thoughts would be appreciated. Thanks!
Cheers!

Thanks for the replies so far!
I have tried rolling into it as opposed to just stepping on it. No difference. It's intermittent, sometimes it happens rolling into it, sometimes it doesn't, sometimes it happens stepping on it and sometimes it doesn't. I bought this truck in March and didn't have this problem, its just been within the past week or so that its started. Before this it ran fine.
Cheers!

Big Angry Hillbilly; whenever I read the forum posts I always look for your responses first You certainly seem to know these engines!
You are right, it was the ERG valve. Dealership said it was clogged so they installed a new one and a kit with it? Not sure what that is, a gasket kit maybe?
I was wondering if I listed the part numbers if you would be able to explain to me a bit better what these parts are. It would be appreciated;
Valve A Z00 P# CX-2056
Kit - E N10 P# 6C3Z - 9P449 - A
She runs better than it did before it went in the shop so I'm happy. I read a lot on the forums here about guys cleaning their EGR out, I'm assuming thats different then the actual valve?
