Battery has been changed, coils changed, and the 1200 stilll has same issues. It will start well and run great for 2-3 hours then all of a sudden it will shut down. I am able to restart and limp back home when it happens with the help of 1/2 choke and light throttle to get home. Next day it may run normal and do the same thing, or it may run poorly even when just started???
