Its tough to tell, for some reason I would investigate a fuel issue 1st. If I recall its easy to pinch the fuel lines on those bikes as I believe it has a remote petcock. If you could create the situation near you house, check your plugs and you would have an indication if you lean by white tipped plugs.
Note: on this bike (as well as most others) its not a good idea to turn off the motor at 60 mph and hold the clutch and coast to a stop for this test. Although it will give an excellent plug reading the problem is created without the engine running the clutch push rod gets hot and can cause some issues.
