Things that have been tried so far to resolve the issue with my throttle cutting out/misfire:
Spark plugs, wires, and fuel filter were replaced a couple months before the issue started happening but have not been replaced since.
The rest of this list was done after the issue started.
Swapped the distributor for a different used one from the junk yard. ICM and Coil look to be in better shape than my old distributor, but no change in performance.
New Cap
New Rotor
New Air Filter
New Head Gasket
Tested the TPS (tested good)
Swapped throttle body with a different used one: Used TPS and MAF with no change in performance
Tested fuel pressure at idle and revving with and without vacuum (good results)
Set ignition timing
removed exhaust from the header back (to test if the cat was clogged)
Turned off the switch on my j1 jumper to use my stock p75 maps
Swapping the ECU with another
Swapped the main relay with a known working one
Swapped the fuel pump with a known working one
Drove with the O2 sensor unplugged (no change besides cel)
Drove with the IAT Sensor Unplugged (no change besides cel)

When the car is cold I can feel a hesitation and usually misfires around 5k. Once the car warms up, the throttle cuts out completely at anything more than 1/8 throttle.
