I don't know much about wine yeast, I only work with beer yeast.


Going back through, I noticed you say 'the average temperature" How big are the temperature swings? You don't want much variation in your temperature otherwise your yeast will go dormant even though the temperature is ok. Everytime the temperature drops the yeast get ready for "hibernation" and could drop out of suspension, then when it comes back up, they start feeding again. Keep as constant a temperature as you can.
