Turbo Busa intermittent poor running

Hey guys, I have been battling this problem on my turbo busa for about a year now and am finally getting to my tipping point.

At first I thought it may have been my stand alone fuel management system and/or my harness, so I went back to stock with a pc5, a new harness, and I am still having this problem!

I can start the motor and it will run GREAT at times. Then if I shut it off, and restart it...it runs lousy. It won't rev, sluggish, popping, etc. It may take 5-10 re-starts before I can get it to run good again.

I have no idea what could be causing this. Ideas?
