You may have a problem with the catalytic converter creating too much back pressure and it may need to be replaced. This would create the bogging that you are describing. Do you notice any odor or excessive heat when it happens? I recommend getting the code read and go from there.
yes the car start to overheat the cat almost 20 years old
yes it the CC I had the exact issue ... runs fine at low speed but try to accele. forget at idle you can feel the restriction from the muffler
