Beany: I mentioned fuel filter since you said it had been replaced. Often when new issues crop up it's after something has been done to the car. I would not ignore the fuel filter issue. Run that to ground. Also, I did not note this before but what about that fuel pump? It that the correct pump? Afternarket? Verify that is or is not the problem too.
I'm always skeptical when work has been done on the car and then a new problem shows itself. I always go back and look/verify. Is it the new part or parts that's the problem? It is plausible for a new part to be bad out of the box.
The conditions you noted sound to me like a fuel-starved condition.
If no then an intake air restriction of some type.
Let us know what you find.
All the best, Haya....
