1993 5.2 magnum engine problems

[69wssdart]

My '93 dodge ram d150 5.2 magnum is having engine problems. When i start it it runs fine for a few minutes but you cant rev it. after a while it starts to lobe and and idles down and you cant give it any gas it just bogs. ive checked fuel pressure under load and checked spark. iv checked the fuel filter. nothing so far. to me its like its flooding and a friend of mine says it sounds like its starving for fuel. ive checked all the vacuum lines and there fine. i just cant figure it out. so please if any one has any ideas please help i need it.

So....engine codes?

its not throwing any codes and if its a cloged cat why dose it run fine till it warms up. coolant temp sensor was replaced today still no good.
