no power when warm

i hate to star another thread but i need to get this solved. i have a 91 runner with a 22re, and when my truck is cold it runs great but after about 4 min or so of driving i have no power the only i can accelerate is with the pedal to the floor. i can even hold 50 in 5th on flat ground unless i have the pedal on the floor. i think it ether the o2 or the coolant temp sensors but i dont' want to just throw parts at it any thing else i should check? this is what's been done recently new plugs, wires, fuel filter, cone air filter, new exaugst, new clutch, cleaned and tested injectors, the timing is at 7-8 BTDC timeing chane has maybe 50k on it.

Thanks
-Tom

You should be getting engines codes. Does your check engine light work?
