Rheem PVR50-80 Hot, cool, cooler, cooler, HOT. What's the deal??

I have a 6 year old Rheem PVR50-80 gas water heater. For the last two winters, I have noticed (especially in the shower) that the water starts to get cool within a few minutes of being turned on. In the shower, you have to keep turning the faucet in the hot water direction to keep the water warm. Within 7-10 minutes, the faucet is turned totally to the hot water side and the water is chilly. Then suddenly the hot water comes back on--you have to jump out of the shower and turn the faucet back in the direction of cold to get the water to a bearable temperature.

Could this problem be related to a gas supply issue? An issue with the gas supply box/junction box (or whatever it's called) . . .

Thanks

Is it only happening to this shower? What about the other shower or faucets in the home?

Rheem PVR50-80 water tank

Hello
If your water heater is used for heating your house as well and suppling hot water, your problem is likely to be the water mixing valve located above the unit. It usually last 5-6 years.
Replace it. Home Depot sells for $100 including taxes.
