It sounds to me like the jetting; I had a similar problem on my 06 (though it never dies in the air). Since I re-jetted it and added a quick shot it hasn't happened again; I recomend getting the JD jet kit, you can find it in the TT store.

my 05 does this to sometimes, especially after coming down a hill, i don't know what it could be, I have a quickshot on it and I think its jetted right, anyone else have any ideas.

It is a new Accelerator Pump Cover from Boyesen; it improves the throttle response and diminishes bog very well. They are about $85 and you can get them at most places.
