General Fuel cut off of idle

When i go to accelerate anything under 2000 rpm under a load the afr shows fuel cut off and the car tries to die. Only happens when im stopped and im trying to move
 
-Big vac/boost leak
-faulty fuel pump
-faulty FPR
-gas leak
-clogged fuel filter
Alot more issues could cause this.
What is your base fuel pressure and does it rise with the engines rev just before it cuts fuel?
 
Drives fine after it gets going pulls amazing in boost. vac is 16 to 18. I have boost pressure set to 13 to 15 psi. It has a manual adjustable regulator. Car idles at 38 ish psi doesn't jump much under acceleration but from what i seen it goes to 40ish on fp guage
 
Well im sure it does but that not where im having a issue. My issue is my car tries to die while im leaving a stop sign and i either have to rev the piss out of it to keep it from shutting while taking off or i have to let it choke through take off untill it decides to run.

I also never let the rpm drop below 1200 while im letting the clutch out
 
Fixed the problem pulled tb off gave it a good clean. Set the tbs off the car. Changed biss oring and readjusted now just to fix the knock issue
