Possible HPOP?

I got my truck running after chasing a bad icp, ipr uvch and pcm (so I was told) got her back running and has been driving good for the last couple weeks untill a couple days ago. The truck runs fine in the morning on my way to work, 30 min drive. It sits all day while at work and when I leave I go start it up, starts like normal, let it idle for a minute or so while I get settled than I drive off, the first couple minutes of driving I'm going under 25 once I hit a 45 zone I go to accelerate and the truck starts missing similar feel when my cps went out (replaced that too with the old style purple one) its does this it seems for just a little bit and only a couple times and than I'm on the highway going 60 and it drives just fine the rest of the way home.

I got to thinking that the only difference between when I start the truck in the morning to when I start it after work is that in the morning i let it "warm up" for 5-10 mins than I'm off, and when I leave work i let it "warm up"for maybe a min so today I let it "warm up" after for 5 mins just sat there and waited 5 mins later I drove off and no miss at all truck drove great.

So the only thing that came to my mind is letting the truck "warm up" is allowing the hpop to build pressure and when I just drive right away it has no pressure right away, am I thinking correctly on this or could I have a different problem. Thanks for the help as usual, side note truck starts with no problem, does have a "romp" for a couple secs than smoothes out.
