1993 Oldsmobile Bravada 6 cyl All Wheel Drive Automatic

I have a 1993 oldsmobile bravada. When is cold it runs ok but when it warn it runs real bad. when i press the gas more then half way it boggs down almost like it needs plugs but i put plugs and a new distributor cap on it. the hotter the motor gets the worse it runs
