It could be the brake switch for the safety devive so small children can`t get it out of park unless the brake pedal is pressed but could also be a misadjusted shift cable ...after car has run it must be heating up something possible to help shift
your key cylinder could be the problem too .....I have never hear of one coming out of adjustment unless someone has gone into the steering colum recently ...but key won`t go into off position unless car is in PARK ...cable problem binding possiable
