Wednesday while riding my sporty would backfire spit and sputter then die. Would not start back up for about 15-20 min. Did this several times throughout the day (Hwy Driving). Was told that the coil was probably the problem, so bought and installed a new coil drove around town all the next day. Today doing it again, went 60 miles and it died, waited about 20 min and it started backup, drove about 20 miles did it again, then did it several more times before I could get it home. I'm thinking now that the ignition module is bad. Any input would be helpful, as this is my first bike and I'm new to riding, so I don't know squat. Thanks in advance.
