97 yukon bogs down when warms up

i have a 97 yukon that when i hit the peddal hard it will bog down and dont want to go after the engen gets warmed up. when the engen is cold it runs perfect. i have changed the fuel pump 2 times the fuel filter and the fuel pressure regulator and plugs wireing and cap and button ang the heat sencer by the thermostat. anyone have any idea where to go from here? thanks for any help you can give me

May be a bad cat, disconnect the exhaust in ft of the cat see how it runs. Also you could do a full scan and check fuel pressure when this happens you need 65 psi.

i was just getting ready to try the cad tomorrow. i have replaced everything i can think of on the fuel so im guessing it wont be in that i replaced the fuel pump 3 times in the last 3 months and i had a scan done and it dont show any codes.
