Thank you... realized after post probably not enough info.. I have price pfister, single faucet... this is stand alone shower.. tub in bathroom works fine.. this was not a gradual occurrence... worked fine first shower yesterday, then no hot water second shower an hour later... I have taken off the handle, but can't seem to get the plate off... not sure what to do if I get the plate off but have been reading different posts and am wondering if this could be a mixer problem...

The sleeve screws on to hold the trim plate down. You may have debris in the valve. Flush it out and rinse the cartridge.
