Low Hot Water Pressure/Cold water pressure Okay

I have an AO Smith 90 gallon gas heater. I believe its 10 years old. Recently I have experienced low hot water pressure throughout the house. I can fix the problem by activating the P/T valve for about 5 seconds. This fixes the problem for a week or two then I get the low pressure on the hot water line again. Cold water pressure is okay all the time and measures about 50psi. The P/T has a very minor leak. Any ideas how to fix this? One other bit of info: the AO Smith heater is part of a 2-heater system which are connected in series with the AO Smith heater being first in the series. Thanks, CB
