bike just quits running ..i wait for something to cool down or reset itself ,,, usaully about 10 minutes or more..and then it will start right up ..and go at this pattern again ..after it shuts off i checked for spark... no spark ...the bike is a 1999 ..with 24000 miles on it ..i keep it in the garage ..all grounds look great ..all wireing looks good ..any ideas please.. it just may be the coil? or could it be the main breaker ..ignition module is not hot too the touch..
