Been dealing with intermediate stuttering problem for awhile. Things have kept me from getting to the fuel pump but have rode and tried to eliminate other possible causes. Overrode the tip over sensor and kick stand sensor and problem still happens. Usually after a hour of running where bike just falls flat on its face in moderate or hard acceleration shifting from 1st to 2nd or 3rd. Will sometimes stall under hard braking. Already tried seafoam more then a few times but problem still returns so i don't think its anything in my tank. Thing is the past couple of weeks have been cold. Warmest being 65 degrees. Have also switched from 89 sunoco to 93 BP. Outside temp when getting home has been as low as 48 degrees. Thing is the bike has run GREAT throughout these cold temp days. No stuttering whatsoever and it has been run hard and the gas tank ran a quarter away from empty. Before this cold snap we had one warm day (85 degrees) and after a hour or so of easy running the bike started acting up again. Got in traffic for a bit so it got even more heatsoaked. Was about a half mile from home and just cruising when i shifted into 3rd and the bike stuttered and bucked worse then ever about 4 times then died. Pulled over and tried to refire it 4 times with no success. After thumbing the handlebar idle adjuster up a bit the bike finally restarted and I nursed it home. Once again in cold weather riding it has been excellent. Today it was a high of 82, tank was full of 93 bp fuel and after a hour of riding it started up again. Same power loss between gear shifts and stalled under hard braking at a light. The FI light never comes on and no codes show up on display (haven't done the paperclip mod though) when this happens.
Can this still be a fuel pump issue or a heat sensor gone bad? If it was the pump going south or clogged screens then why has the bike ran like a champ in daytime temps of 60 degrees or less?? If it could be a temp sensor going bad which one should i go after?

. any suggestions
