I highly doubt that demigods can lose their powers. They can lose some minor abilities (like Curse of Achilles or Blessing of Artemis) but not the ones they were born with. If Percy lost his powers then it wouldn't make any sense. Plus many might disagree with me but those Water Powers are a big part of Percy. If he lost them then Percy would be meaningless in the demigod world.
