True, no bearings in the dizzy, but there is a "bearing surface" that get's marred up pretty badly. When I had mine apart, I sanded it smooth and put a light polishing job on it. Then it spun nice.
My Problem is now 10X worse

I'm gonna go along with these fine gents and tell you your dizzy is shot. I speak from personal experience, and if I could find the video I have of the car breaking up, I would host it and post it. I tried EVERYTHING to try and fix this. I literally tried every single thing you tried plus some more things because I wasn't sure if it was an electrical problem or fuel. I went to Autozone and got a remanufactured dizzy for like $70 and it worked like a charm. It was like $30 for the PIP stator itself, and I bought it, took it home, and decided to just get the whole distributor.
Take the cap and rotor off. Is there a pile of tiny metal filings sitting in the bottom of the diz base?

Like this?
I took a video of it breaking up awhile ago but for some reason its not on my youtube or my photobucket. I'll down load it again and post it up.
Here is the video of the problem as it started. (pics are on the last post of the previous page)

there's 4 things that have caused that problem among the 94/95's I've owned, Coil, Dizzy/PIP, Fuel pump, and dirty MAF. If none of those are you problem, then you have a gremlin somewhere.
Tried it w/ the fuel pressure jacked up and it still did it, Tried 2 different coils and it still did it, had the meter out in the last few wks and it is not dirty. The only thing left that has not been tested or replaced is the dizzy

Ok, if the dizzy does not fix it, you'll need to see a fuel gauge while driving it. Giving it all the fuel pressure in the world while idling won't make a bit of difference while driving. If you're ignition system is up to par then start looking into fuel.
How old is your fuel pump, ever changed it?

I know it wont make a bit of difference at idle but it was turned up by 10 PSI and it still had the break up at 4,000 RPM's. Its a 255LPH pump it was changed before I got the car so Im not sure when exactly.

Its gotta be your diz. Mine looked kinda like that when I changed it out. Not necessarily a legit pile of shavings, but scattered metal shavings throughout the base, which is what your pic looks like. Get a remanufactured diz and see what happens. Guarantee that is the problem.

ok back to square one.
I got it running again but it still breaks up at 4,000 RPM's.
For some reason when I put the different ECU in it caused the tune in my DBX digital meter to get erased so there was no tune in the meter and that's why it would start up and then stall out again. I took it out for a quick spin ( in the rain unfortunately) and it still had the stumble at 4,000 RPM as in the video. Theres a guy on another forum Im on w/ a 351W distributor so Im going to try that and hopefully it fix's all of this crap.

it was kinda fun spinning the tires on the wet tar though 
You would never think this is Maine for the past 2- 2 1/2 weeks, its more like Seattle weather. Non stop rain and over cast cool temps. At least its all been happening when the car has been down or not running correctly so Im not really missing much track time.
