Losing power

I have a 03 F250 v10 4x2 once it warms up the beast loses power or just won’t go. But when it’s cold I can floor it and it gos. So far replaced cats plugs fuel filter mafs sensor fuel pressure sensor throttle body removed and cleaned and still having the same problem fuel pressure tested fine I’m so lost now

Habe you plugged in a scanner to read the codes, pending codes and other useful engine parameters?

Also, what exactly happens when it is warmed up and you depress the accelerator...I mean besides a vague description that the truck won't go.
