I've got to do a lot of riding lately and all seems well. But, I finally got a chance to ride to work (been many days with rain in the forecast) and it did it again. Has me thinking that it has to do with the auto dimming feature, as it is dark when I ride to work. This time though, the display came back on, after a few miles (and it seems I hit a bump, at the same time) and it has been functioning properly since.
I guess we will see if the issue arises again. I started the bike in the garage last night, in the dark and it was all good. Going out here in a little while and it will be dark when we head home. See what happens.
