Hello. If the vehicle only does this while going uphill and no other times then it is usually caused by a failing catalytic converter or a weak fuel pump. Both of these will cause this as well as a failure in one of the sensors.

I usually start by scanning the computer for codes to see if anything comes up. If not then I monitor the sensor readings and check the fuel trim readings to see if it is a sensor issue or a fuel system problem. If nothing comes up there then I check the converter.

If you are going to have this loss of power inspected, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this problem.
