Make sure the gas valve is turned to the "On" position after the pilot stays lit. You may need to replace the thermopile. Some units have a thermopile rather than a thermocouple and it will not allow the gas valve to open if not enough voltage is being sent to the gas valve. Hopefully your gas valve is working properly and will not need to be replaced.

Make sure all the wire connections are good and tight. Next lift off the cover and look for a little thermal disc mounted up by top of the heat exchanger. Most have a re-set button but not all. If you have this ,by-pass it ,see if that solves the problem, if so it may be defective, or doing its job and you have a venting problem. If you don't have this and have changed the thermocouple (was it a copper tube with a fitting that screwed into the gas valve, or did it have 2 wires, that is a pilot generator, kind of same thing) make sure the probe is set correct, with the pilot flame heating the top 1/3rd of the probe. The only thing left is the gas valve.

the problem is the thermocoupler. it is the other small tube next to the pilot light. this tube sends a signal to the main valve to let the fuel go through. sometimes you have to change the whole pilot unit.

The pilot orifice could be dirty causing the pilot flame to be too small. Unscrew the pilot tube at the pilot assembly. The orifice is inside. Remove the orifice and blow it out with compressed air only. Reassemble and see if that fixes the problem. If the pilot flame is set too low, sometimes opening a door will cause a draft to blow out the pilot. If the thermocouple is good and the pilot flame is set properly, the control valve may be bad.
