When my car shifts into third or fourth I lose power and when I sit at idle it almost wants to stall. what could cause this? I am going to change the fuel filter tomorrow.

This could be fuel related as you are talking about however, we need to check the pressure once you change the filter.

Here are some guides that go through low power causes:

Let me know what you find with the fuel pressure and we can go from there or if something else sticks out from the guides.
