after I replaced CPS, as per P0322 instructions, stall and tough starting problem remains the same.. Starts right up ok when engine is cold.... idles for 15 or 20 min then stalls ... wtf?

Could be the wiring harness, usually changing the CPS resolves the issue. But since you are still experiencing the same issue, try checking the wires, make sure they are not frayed or corroded. Then try switching the Camshaft position sensor if your wiring looks ok.
