RE: Need technical help!!!!
Have cleaned MAF 3 times, 2 new fuel filters, tried all different fuel pressure settings and no better!! I have attempted all of the easy fix things many times with no results.

I wouldn't replace the ecm until you can narrow down the misfire to secondary or primary and I can't remember cause it's been such a while since I've used a obd 1 scanner on a ford..but I'd look to see if you can get a data stream..on the modis we can get somewhat of one.. but look for a pid that has the timing shown

Yeah i know what closed loop means i just wasn't sure if it had to do with coolant temp. Is there a way other than holding the light in the engine bay at 5,000 rpmto check total timing? Should i try replacing the ecm?

The only EEC-IV V8 Mustang generation with datastream capabilities is the SN95. Since the symptom is time/temperature related, you may want to check the PIP/SPOUT signals combo....... if you don't have access to a scope, you could take the SPOUT out of the picture by locking the distributor to ~36° advance, leave the SPOUT connector off......and see if the problem repeats after an extended drive cycle test.

RE: Need technical help!!!!
It was theTFI from o'reilly auto parts? Yes i used the dielectric grease. What else could this be besides the ECM? Even tried a new distributor today and that did nothing. The car runs good and has no other problems besides cutting out at high rpm after about 20 mins. When it runs good it is a big difference from when it is sluggish and hot, it feels like two different cars!
