Sounds like the problem I had last January.  The problem started with the hot
water running out very quickly, which was unusual.  Normally we could take
4 showers in 2 bathrooms and not run out of hot water.  Then all of a sudden,
we couldn't take 2 showers without running out of hot water.  Then the faucets
started to have decreased water flow and pressure.

As others said, the problem was the dip tube dissentigrated.  The tiny pieces
blocked the airators and since the cold water was income in at the top of the
heater where the hot water was, the hot water was being deluted too quickly.

So I replaced the hot water heater and that solved the hot water issue.  Then I
had to clean out all the airators.
