Frogger is right on! I had the same problem with one of my Cannon Mag 10, I sent it to Lake George Fish 307 and received it back in two days, as it turned out, the connection to the spool wasn't right making the auto stop to work. Cost me like $27 but could have easily fixed myself if I knew what the problem, was. Easy fix trust me. I believe the coated cable needs to stripped back assuring the connection at the ground. Good Luck.
