Why would a 2002 Honda shadow run good for miles at a time and then suddenly die even on a full tank of gas?

floats may be sticking in carb fuel filter may be clogged or gas cap vent my not be venting if this happens again pop open gas cap and listen for air pressure if you here it find vent and clean out with carb cleaner run carb cleaner in gas did you do any work to bike rejet carbs
