do a compression test, and if thats good then do a fuel pressure test. does it miss fire at all or loose a lot of power while going up hill?

That sounds/looks like a problem with engine timing data. Replace the CPS with a new part and see if that helps.

When am punching the car, as my rpms are going up it stall/cuts off at 4000rpms for just a second and then it will pick up and continue as I was punching. But it doesn't happened all the time.
