APC is unreliable.

You probably hit the fuel cutoff which occurs (at least in my '91 9000 Turbo, although it may be higher for your car) at around 15psi. If the APC fails to regulate the boost enough to keep it below this level, then the fuel cutoff steps in as a safety measure.
The APC is designed to regulate boost, but it is not faultless, perhaps your APC solenoid is failing.
IMHO, if you always use premium gas, the APC is unnecessary anyway. You can replace the APC solenoid with a manual boost control valve that will never fail, and also increase your performance.
You can buy these valves for about $80, but even that is unnecessary.
I designed a valve for my car which (once I had it set correctly) has performed flawlessly for months now. The turbo spool up is faster = more low end torque etc. etc. It cost me $10 in parts from the hardware store.
If you're interested, email me and I will explain how to build it.
