    If your car is running I doubt its the fuel pump. The first thing I would do is change the fuel filters.

    You may also have a faulty o2 sensor, or bad coolant temp sensor, hook it up to a reader and monitor engine data.

    Second thing to change is aircleaner filters. I had a diesel and that was a big problem when the airfilter was dirty. Once I lost a lot of power running uphill. I stopped and looked under the hood to see the air duct was going flat when accelerating. I opened the air cleaner and found a big dead rat that was dried out and suck to the entrance of the aircleaner as soon I accelerated.
