    Hot water turns Cold - Moen Single Handle Shower
    We have a new Shower (no tub) that used to work just fine but now, after a few minutes of hot water, the water comes out cold. If we turn on the tub (seperate facet) then the hot water returns.

    Sounds like hot and cold balancer is sticking. Take out cartridge and balancer and shake balancer and see if it rattles to free it.
