E-nut, Welcome to the forum! Another veteran rider seduced by the Duke's charms!
Your stalling issue sounds very much like it could be the result of a misbehaving sidestand switch. As CDN mentioned, the first step in the fix is to thoroughly clean the magnet mounted on the sidestand, as well as the sensor/switch activated by the magnet. The second part of the fix developed by Hoover is to take off the magnet, add a washer and reattach it so it will now reside closer to the sensor when the stand is retracted, reducing the chance that movements and vibrations during operation will move the magnet out of range of the sensor. Everyone who has tried this fix thus far has been pleased with the results.
There may possibly be other causes for 390 stalling that will not be addressed by this fix, but certainly experience suggests that a great percentage of stalling issues can be cured with this simple solution. Try it!
