My first thought too. IIRC, the 944 has this as well. The only problem is why it would continue to die even with throttle applied but below the 3k rpm. Wild hare-brained thought but, what about a plugged cat? The reason I ask is because it restarts fine, leading me to question exhaust flow. If the O2 is bad maybe there is more wrong in that direction.
