When Im riding after about 2 min the speakers cut out. Turn the 3 way switch from speaker A to speakerB they come right back on then cut out 2min later. Go back to speaker A they work for another 2 min. did self diag on radio and found no fault codes. Problem only happens while riding. Tried to repeat prob while standing still by shaking harrness as many places as I could get to and couldnt get it to repeat prob. Any help would be appretiated, its driving me nuts hitting the switch every couple of min just to listen to the radio..
