Default Problems at 3500RPMs when warm

I have an automatic 2000 GT. So when I start it up, it runs fine. Pulls hard all the way through the power band. Then the engine gets to temperature, and thats when things start going downhill. I'll be running at really any speed, I'll floor it, transmission downshifts, rpms go up, but it doesn't pull. But then, I'll let off of the gas, the trans will shift back up, rpms go down below 3500 and it'll slowly accelerate. But it progressively gets worse as I drive it, until it won't pull at all and I have to pull over and shut it down. However, wait 30 seconds to a minute and start it back up, and it's back to where it'll pull up to around 3500 for a while. I went another 15-20 miles yesterday after doing this and only stopped when I arrived at my destination. HELP!!! It's got me stumped, and I can't stand the lack of power. (getting passed by Honda Civics and such hurts the pride)

Sounds like clogged catalytic converters to me.
