Are you sure you are not talking about the CPS (Crankshaft Position Sensor) Item # 7 in the first pic located in front of the Oil Filter or the Twist Grip Sensor Item # 2 in the second pic located in the Handle Bars?

If you're referring to the Throttle Position Sensor, I don't believe it exist. You have a TCA, (Throttle Control Actuator), which is the black electric box on you TB, and HD doesn't sell that separately. Do you have a manual?

Is your throttle smooth and powerful ? Just trying to separate mechanical and electrical problems. Have you replaced your compensator ?

Just out of curiosity, how long have you had this problem, and how long have you had the TMax, have you changed your MAP or done anything else recently?

Are there ant DTC's ?
It is highly unlikely that the crank went bad on you when you stopped for lunch,
if the crank was going bad it would have shown signs of it long ago.
My bike shakes like a nun in a whore house when idling and it always has since new so shaking at idle is what the rubber mounted "A" engine does.
Did you check the front motor mount??
