I recently started experiencing this, my Pilot is 18 months old. So far it has happened mostly when plugged into a charger. So I thought the usb connection might be going bad. But since then it has happened once or twice operating off the battery. Now I don't know what to think. Probably will buy a new battery and see if that makes a difference.
I don't know what I will do if the Pilot dies. Doesn't seem to be be anything on the market with such a rich set of features. Have been sizing up the used Pilot market but I don't feel very confident going that route, not that there may be any choice.
