the pilot has a igntion switch but that's not the issue I've done all of that,when you go to turn the knob to the on postion that is when the pilot goes out. I have repeated the steps atleast 10 times with no luck. Do you have any idea what the problem can be??

"my mother has a new heating system, her pilot light will not stay on long enough to switch to the on postion, as soon as you let the button up it shuts off and I am trying to save her some money."

If it is new then it should be underwarantee.

So, every morning I relight the pilot light on our water heater. But after the water is hot the pilot light goes out.

It lights real ease, I don't even have to wait the full 60 seconds for it to stay lit (usually stays lit within 3 or 4 seconds.) Everyone takes their morning showers and has hot water.

Later when I go to wash dishes or wash clothes, no hot water the pilot light is out again. Only now I can't get it to stay lit, even after holding the gas control knob down for 5 minutes or more.

I thought maybe that the pilot light was being blown out when the burners went out so after lighting it I tried turning the thermostat on and off. But the pilot light stayed lit.

It seems to only be a problem after the water in the tank has gotten warm.

Any idea what's wrong?
