My Jeep under hard acceleration will lose power. Under light acceleration it will shift smooth and when you go out to pass and put your foot into it, it loses all power engine will rev at 4000rpm. You let off the throttle slightly and it takes off normal until you accelerate hard again. This only happens when vehicle is operating condition. Shut the Jeep off for 20 minutes or so and you can get in and it will shift normal till it is warm. No dtc’s Detected. Has anyone had this issue.
