+1 on the charging possibility. Since your battery was showing problems
that sounds suspect and just like something I experienced. Bike bogged and died at about 45 mph and wouldn't restart. Regulator/regulator (on bottom of battery box) was fried. You might want to read thru the Stator Papers. Still you need to get used to the idea that you'll be working through the other issues listed above to get the bike reliable even if it does turn out to be a charging issue.
