Unhappy engine hesitating and then shutting down at idle

I have a 03 VN that a couple of months ago. The previous owner had let it set up. The first time I took it out it died on me and I had to trailer it home.I had the carb cleaned and the bike has been running good. I took it out on about a 20 mile round trip this past week. It ran good to my destination. On the return trip I noticed the engine skipping. I was going down a highway so it was skipping and I had the throttle all the way open and it was barely getting up to 55 mph. When I came to a red light the engine just died. I tried to get it cranked and it would crank and just die. I had to use the choke to crank it and keep it running. It was still running very bad. I had to get someone to come and get me. When I got home I was looking at it and making sure all the hoses were connected. I cranked it back up and it ran good. I am mystified. I haven't had a chance to take it out on a ride but just cranking it and revving it up it is running perfect again. I don't really know what was wrong. I figured I would put this problem to all the VN experts on this site. If you all have any ideas I would appreciate ideas.

Might be POOGS... especially since you started it later and it ran fine. If it dies again while on the move, pop open the gas cap and leave it open for a minute then try to start the bike again and see how it does. If it runs fine again it most likely is POOGS (phantom out of gas syndrome) and you need to clean the vents in the gas cap.

You sure you had enough gas and didn't need to switch to reserve yet? That sounds like what happens to me when I need to switch to reserve.

Poogs is definitely a possibility. You may want to look at theright side air cleaner. Theres a vent hose that hooks to it and it can end up stuck flush against the inside of the housing. Cut the end of the house at an angle to prevent that from happening. other than that it sounds like you're getting a lack of fuel situation. Could be a dirty pilot jet. When it acts up I'd pull the plugs and see what they look like.


Jetted, shaved & coastered
Home made under-tank single filter
Converted ACCT's to manual (thanks wib714)
Dual vac lines on petcock (my cure for ticking)
LED tail/plate lights
Relocated helmet lock to license plate

Added stuff:
Customized hard bags w/ lights
Chrome levers
Hellcat windscreen
LED running lights
Home made 'Vita-Volt' meter
Foot rests on engine guard

Hmm....she was on the back when we left.... ??

After reading the comments I think I might have POOG. After I posted my question I saw a post on POOGS. I went out and worked on the vent. Thanks for helping me. I appreciate it very much.
