Sounds to me like the gas orifice is partially plugged. Or your burner is dirty and should be cleaned.

If I understand correctly, the pilot light is not staying lit.
You light the pilot and water in the tank reaches temperature.
Once hot water is gone, then pilot light has to be lit again.

Gas pressure is good, and gas is flowing.
Thermostat is working at high end because it cuts off heating.
Vent is working because tank heats up.
Air intake is working.

Gas control thermostat might not be reading low temperature. Replace gas control valve.
Pilot tube might be dirty. Clean burner parts and combustion chamber, and air intake, and vent.
Backdraft might be blowing out pilot. Check for constant updraft by running water heater 5 minutes, and then light match under vent hood and see if smoke goes up.
Very hot air can put out pilot, especially when water heater located in attic. Add ventilation.
Improper vent might have water dripping back down into combustion chamber and putting out pilot light and rusting out the parts. Inspect for rusted parts and water.

The water heater is leaking, probably because of its age. Replace it.

Reliance Natural... | Answered on Dec 09, 2013

there is a lot of controversy over this. The reasons that you may want to do it are because of cathodic erosion. If the water has high mineral content it can shorten the life of the tank. If you are using plastic pipe in the house it can affect the situation also. All that aside, the reason for the grounding is found in the National Electrical Code and is in section 250.140 . The reason is that the code calls for grounding of all other metal piping systems that do not carry water. That would mean the natural gas line! The reasoning is because if something happens and energizes the gas line and it is not grounded it could cause a fire or an electrocution hazard. The code calls for a ground wire of sufficient size to handle a stray voltage of the amount that would be most likely found in the application. So you have 220 VAC in most residential applications. That would mean that you should use something in the neighborhood of about # 8 to # 12 AWG as a ground. There are charts to determine the exact size. IT depends on the length of the run.. The wire should be connected to the area closest to the control head if the head is not insulated from the pipe and then run to an electrical ground nearby. The installation has to be done by an electrician and not a plumber unless you do it yourself IF YOU ARE THE OWNER OF THE HOUSE AND IT IS NOT A RENTAL.

Copy following links:
Reliance is made by AO Smith company, and air intake located on bottom of unit.
Make sure you have adequate incoming air and vent is working.
Remember, the pilot is located upwards from the viewing sight-glass, so it is sometimes difficult to see pilot.
Pilot flame must burn clear blue, with bits of yellow and red. Yellow flame means inadequate air supply or venting.

1) Bad gas control thermostat, or thermostat has come out of calibration, or water leak running hot water out of tank.
Turn up temperature.
Replace gas control valve.

2) Clean air intake, put ear against pipes and listen for water leak, check that flame is clear blue and that combustion gasses are flowing up the vent pipe and not blocked.

3) Call service technician.
