Maybe the PCV valves on the intake manifold have given up. Does the car ever stall out when cold, before it has gone into closed-loop mode? If it was a vacuum leak leading to a lean condition, my guess is the car stalls when warmed up or when the car goes into closed loop mode. In closed loop, a vacuum leak will lean out the engine whereas in open-loop, the extra air may be balanced out with the extra fuel.
