No chain,
Just wondering if maybe your fuel pump is failing and that it is just coincidence that it happens at fairly high trip mileage? (One reason I would not suspect this is due to the long period between symptoms??) I have not experienced it myself but if you search on this forum you can read about others who have...seems their bike will shut off just like they have run out of fuel only to find the bike will restart after sitting for a few minutes..I witnessed this at the '09 rally when it happened to Brian. Just a thought if you are stalling at mileage that seems to low to need reserve. On my T it seems that fuel mileage is proportionate to speed, out on the freeway any thing over 65 mph for extended periods and the mpg takes a dive at 75 mph average I will lose at least 10 mpg. At this mph/mpg I am hitting reserve around 105 miles.
