Car is a 91 NA:

Everything seems to work fine until the engine gets to ~130 degrees or so. At this point any application of throttle causes the engine to miss and begin stalling. It will still idle in this condition. When the engine is cold, it can rev just fine, no stalling at all. With the TPS unplugged at temp, this does not occur (poor throttle response but no stalling). I had to piece this car back together since my daily driver died, so it is in slight disarray. I have the TB coolant passage bypassed, most of the vacuum spider is gone, omp blocked but still plugged in . Vacuum leaks have been taken care of. Something is changing once the car begins to warm up to not allow acceleration. The TPS tested to be fine. I'm really racking my brain here.

Any ideas are greatlly appreciated.

Get to the ECU and read out all of the sensor inputs...

Sure you have no vac leaks once she's warm?

I have checked and found nothing noticeable when warm. Thanks for the link. I'll provide an update tomorrow.
