The first thing to do is check trouble codes. If you can't limp the thing to AutoZone where they'll check the codes for free you can buy a cheap CAN enabled code reader that will read the engine codes at almost any parts store or Walmart.
If there is a difference between commanded throttle position and actual position it will go to reduced power mode. My CTS used to do it all the time when -40F weather would hit. All I had to do to clear it was shut it off and restart it.
Good luck. It shouldn't be too serious a problem.
