Check your VSS (Vehicle Speed Sensor) on the Tranny it could be bad or unconected or has just failed. Take it out clean all connections and plug back in if stall continues change it. This sensor tells the car that its slowing down and allows the engine to compensate fuel ect so it does not drop all the way down. As for the codes not sure what to do there.
