Is the Check Engine Light on? The throttle body assembly is a common failure item on this vehicle and can cause similar symptoms. In some cases, throttle body assembly will not open properly in accordance with the input from the throttle pedal position sensor. I would have a certified professional, such as one from YourMechanic, come to your car’s location to inspect the loss of power in order to address this appropriately.
