I would recommend checking the mass air flow sensor as this is a commonly known part that can cause this kind of loss of power. This regulates the air intake into the fuel injection and ensures a proper air/fuel mixture.
As you may know, when going up hill and altitude changes, so does air density which requires a change in the air/fuel mixture. When this sensor is faulty and this does not happen, you will likely experience this kind of loss in power.
I would recommend having an expert from Your Mechanic come to your home to diagnose your car’s running condition.
