Similar to what I'm experiencing. I can sit there in neutral and rev it WOT with no problems. Runs great, in gear, at idle and easing into the throttle. Even good when accelerating quickly from a standing start. But once it kicks into 3rd, I have to ease into the throttle or it'll start stuttering. And can't get over 60mph without it starting to stutter. Was fine up until a week or so ago, then that started.
