MoeJay, are you sure your juice is preservative free? If it has potassium sorbate it is possible that they yeast will start to ferment but not be able to reproduce which would end your fermentation. That would explain signs of starting then a stall. Had that happen to me once with a cider I was told by the orchard had not been treated. After a spectacularly unsuccessful attempt to ferment I found out that it had been treated. Very frustrating problem.
