Yes, a new water heater :-)

Seriously, unless you've been renewing the anode rod, there's not much  
metal left at the bottom of the tank and it will start leaking soon.

As for the temp problem, if it isn't the water heater sensor going  
bad, I've seen this often with mixing valves- is there a mixing valve  
that would add some cold water to the hot coming out of the heater? It  
could also be the shower mixing valve- have you tested other sources  
of hot water when this occurs?
