Moen diverter--hot water runs out

[cbl]

Have we determined whether there is a circulation system on the water heater?

No external pump was found.

Check to see if there are any other Moen faucets in the house. I have run into a call where some old metal Moen cartridges were causing a cross over even when they were in the off position.
