I would suspect the catalytic converter is plugging up on it. They tend to expand when good and hot and restrict the exhaust. There is testing to confirm it, it's called exhaust back pressure test. It involves putting a gauge on the exhaust in place of the oxygen sensor, then driving the car.

I think you'll find that a new converter fixes this up. Expect to spend $500 or so to have it replaced.
