just a thought: from what I have learning talking to a tuner -running 12 PSI on a stock ECU is close to the limit. I would back it off to 10 PSI and see if that fixes your issue. If not take it to an expert. you might have a fuel pump issue or something more serious.

I read on another part of this forum they could have fuel cut at 12.5 PSI. (this is with stock ECU on twin turbo) Single turbo may be slightly different but its a safe bet thats what is happening. Its a starting point anyway. Other things to look at are the fuel pump( if not upgraded), and your injectors.
