It may be a BPV problem, but it certainly isn't a "classic case" 
insofar as Craig described issue. As you indicated--the classic 
symptom involves braking & sudden deceleration immediately before the 
stallout, but that wasn't mentioned in Craig's post. Anyway, the 
failure of the BPV valve isn't because it "hangs open"; rather it 
stays closed (i.e., provides no bypass), and that causes the throttle 
plate to become (too) tightly closed by the boost pressure.
