Hi
Was it a OEM CPS ?
Mine had exactly the same problem, tried an after market CPS which after fitting still displayed a similar stalling problem... bought a OEM CPS replacement all fixed.
But to make sure as mentioned Star it... My experience with sensors/filters is buy cheap buy twice.

You may have a bad or dirty Injectors, or a high pressure in the fuel rail, you must to measure it , it should be NOT higher than 3.8 bar

If it was the injectors going bad, you could try a very cheap solution that might help. Buy some Techron (think people call it seafoam) to clean your injectors. I had a pretty rough idle and some hesitation when accelerating. I put a bottle (for 20 gallons fuel tank) in my tank when empty and filled it up when fuel, repeat 3 times and it might improve.
This a very cheap solution before looking at more expensive fix/repairs.
