96 F350 Power Problems.... FUEL?

Help Please!

Symptoms:
First start of day(In morning) it'll blow a cloud of white smoke and idle a bit of white smoke for a minute then go away,
Rough Idleing,
Boggs down when I put pedal to floor and want to go(Like accelerating getting on interestate!),
After driving around for awhile, then turning it off to go into somewhere, Come back maybe 30 minutes later, I'll start it up and it will hunt jumping RPM's and stalling.
It will get up and go and get up to speed pretty good if I ease into the pedal.
When it's cold it runs great. I can put pedal to floor and she'll take off, once she gets up to temp I lose all get up and go power. In the winter I even had it blowing black smoke when I got into some icey conditions trying to get out of. I could never get out of some mud in the summer with it driving now that its warm.

What I've Done:
I'm guessing something with fuel. So I got a new fuel filter, changed oil, new oil filter, new air filter, I pulled my primary(front) tank down and checked it out. Fuel pressure is around 60 give or take(i read from a remote guage I put on the schrader fitting) Tried fuel injection cleaner, and tried seafoam. Neither seemed to make a difference but I knew that stuff isn't magic anyways.

My overdrive button and component broke off my gear shift. So I do not not if its in overdrive. Like I said above, when its cold, or even in the winter, it rides fine, but once it gets up to temp, and now that its summer, have no power at ALL, need to ease into the pedal to get up and go. ANY IDEAS?

Well you have good fuel psi at idle being that it's around 60psi. Have you scanned it for any codes?

Not really I ran my superchip on it which scans for some codes but didn't get any from it.

Im getting mixed ideas on what it is. Because if it runs strong when its cold then it can't be injectors because injectors would cause it to run bad entirely no matter cold or hot.. right? I'm taking it to get a compression test done just I want to fix it myself and not have some shop do it and pay out the ass

I'm just thinking out loud here but possible oil cooler problem? It seems to me it's an oil problem since it's happening when the truck gets warm. I know you said you changed the oil and what have you but it's still an idea. Are you getting romps when you start it warm?

Hmm thats possible. Would it cause that many problems? What do you mean by romp? Like jump RPMs hard and stall on startup when its warm

It's kind of hard to explain a romp, it is what it sounds like. You start the truck, and the RPMs fluctuate real quick and it makes a "romp" sound. What I'm getting at is, when you have romps on a warm start sometimes it is a blown head gasket.
