Chevy Pickup bogs out.

I have a 94 Chevy Silverado with a 4.3 v6 TBI. When the engine is cold, it accelerates and runs fine. But when it warms up, the engine bogs on hard acceleration and when accelerating in higher speeds (50-70 mph) If I let back off the throttle, I actually get more power. Weird huh? Also, the engine temp will rise over 210 during bogging at highway speeds. Im thinking obviously the fuel mix is leaning out, but what is causing this? Ive replaced the fuel filter and plugs/rotor already.

much appreciation, Drew

A dirty air filter can cause those symptoms.
