Holly berries turned black and fell off bush. What causes this and is there a remedy?

Usually if the berries start to have problems, it is because the plant is stressed, and it is trying to preserve itself. Check to see if the plant is too dry. These shrubs require more watering during fruiting, and if they do not get enough, the plant will abort its berries. I would also check for pests that could be attributing to this as well.
