P1125 and 1126 codes

P1125 and P1126 OBD code on 2003 Mini. Rough idle and dying. With the following codes P1125 and P1126 “Throttle potentiometer 1 and 2 measuring range or power output problem” (minor fault) and the 1126 (major fault). I changed the throttle module and reset the code using the iCarsoft scan tool. Had to reset a couple of times. The car ran fine after that. 4 weeks later EML light came on. Pulled over and got the P1125 code again. Reset with the scan tool drove another 40 miles with no problems. Starting car after 8 hours park time and the code came back. Reset drove home and parked. Next morning car will hardly run and dies at idle with code P1125 and unable to reset.
