A failing pump could cause the issues but why would it seem to be fine after refueling?
Could the speed at which you filled the tank moved crud away form the pump screen ??
Are your throttle bodies butterfly's moving freely ?
I was thinking I was getting some fuelling issues, while looking things over I lubricated the throttle bodies and all my concerns disappeared.
I'm not convinced I did anything but things are better now.
I'm always concerned about my fuel pump, I'm always expecting it to give up, it has been run dry quite a few times but except for a bad dose of fuel it has never let me down.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
