800 etec hard to start when warm

when its cold it fires with barely touching the start button. as it warms up i have to hold the button. then it started running poor at full throttle and didn't want to start without me holding the throttle. engine temps were around 130-140 when it acted up and it was at a 1/4 tank of fuel
after filling up and eating lunch it ran perfect.

bad gas?
bad plugs?/plug alignment?

any one had this issue

Sounds fuel starved. Maybe has to have more than 1/4 tank to feed properly. Don't think eating lunch had much to do with it.

it cooled down during lunch is what i meant by that..
the running issue sounds like a fuel issue but not starting without holding the throttle wouldn't happen from low fuel, maybe bad fuel or poor spark is what i was thinking

There was a re-flash for 16's 800etec that came out a few months back for this. Take it to dealer and get it re-flashed. Not a show stopper either way. I will say this is the first flatland sled I heard actually having trouble most have had issue starting hot at elevation. too much fuel

Fuel tank venting when you removed the cap did you hear a vacuum release
