Loosing power intermittently

I just replaced my IC pump with a CM30. This is my second CM30. But this time, after barely 100 miles, I started to experience the same situation where
after a 15 minute daytime cruising, I punch it (from 65 and up) and no response. But, I could still cruise even after, just can't produce a kickdown.

From a stop, the car crawls slowly ( even with a heavy foot on the throttle) and then gets going. I'm not sure if this would happen during a cold morning start. I still have to find out. My guess is TPS.
I've also recently changed coolant.

Hey Doug,

pull some codes and see if there's any "hidden" codes stored that didn't produce a CEL. That will likely point you in the right direction.

Thanks Greg, I knew you'd chime in eventually, lol. I know you had your throttle body remanufactured, how's that coming along?
I just disconnected the battery and will let it sit for awhile.
I also have vibration issues that come and go especially during my early morning commute (45-65). I think my car needs an general annual checkup
(Coolants, suspension, fluids, brakes,etc.).
