I agree with it being a fuel pressure issue. It can be either of the the fuel tubes or the regulator inside the tank. I would recommend replacing the plastic housing that the regulator sits in as well. It's about $15.00 from H-D and well worth it while you have it apart.

I had similar symptoms with my 2010 RK... it was more noticeable when going over bumpy roads, and very quickly got to the point where it would die if I just let it idle for a short time and ran very rough.
The wire harness connecting to the TMAP sensor had a broken wire I guess, because when I touched the harness, the bike would freak out and die. I replaced the sensor (as it was pretty gunked up anyway), and I also replaced the wire harness and left a little more slack in the wires so it didn't make such a sharp curve when connected to the sensor.

On the 2014 touring bikes, the style of connector to the induction module has changed. It is now a more fully over molded connector that incorporates the curve of the wires instead of having them be more exposed. Generally this type of change is made to solve a problem, which was probably intermittent connection between the ECM and induction module.

Sounds like a pinhole in the gas line for the fuel pump in the tank due to the fact that it did not start to happen until the bike had used a little gas. As long as the line is submerged in gas it will not sputter but as soon as the hole is in the air it will suck air causing the bike to sputter like that. I had it happen on my softail twice. Bagger is all good at 23K so far. Fingers crossed.

Right - but the engineering change indicates that Harley addressed a problem, which his bike might have - just a pointer to a possible cause.
