Car keeps dieing!, When I push in clutch. Options

[BudmannG]

So here is the story that goes with the problem.

I went out to tune earlier and seen a 91 awd out of the coener of my eye. I thought to myself, I have to go by and make sure that is what it was. So I did that, and yes it was a 91 AWD red with the stupid wing on it like the fast and the furious. So I stopped and talked to them.

After I left there, I went down the blacktop that is close to me. I did a 3rd gear pull and it felt strong and pulled hard. I looked at the log I took from that run and no knock all the way through the power band. So I turn around and try it again. This time my pc had shut down on me so no log. But when I get to the stop sign it is idling way low, so I tap the gas to give it a rev and see if I can bring it back up. Didn't work out like I was wanting it to.

I then pull away from the stop sign and go through first then second. I hit third and laid it to the floor! It took off and did what it was supposed to for me. Then I push the clutch in to coast to a stop and the motor dies. WHY? I don't know! So I coast all the way to my turn and let out the clutch in fourth gear and it catches and starts. No big deal right, WRONG!

I got to the next stop and it dies again. When I got to my drive way it did it again. WHY? I know I got a boost leak at the PCV. But it shouldn't cause this thing to die like it is. I am confused about what is going on. I checked all the settings in DSM Link and they are the same as they have been.

Does anyone have any ideas?

If you don't remember what I am running.
3" gm mafs and translator
front mount w/ hard piping
Hallman MBC set at 19psi
50 trim turbo
44mm wastegate w/ open dump
turbo xs rfl BOV open dump
850cc FIC injectors

The last pull I did it had 2.5 counts of knock at 3200 rpm and went away at 4700 rpm. And my A/F ratio doesn't get any lower than 10.00.
