Only thing left to change is the gas valve assembly.

The thermocouple has failed. It is the temp probe that goes from the pilot lite burner area to the control valve. Go to your local plumbng repair shop and buy one. Most appliance parts stores have them also. Take the old one with you and they will hook you up with an exact replacement. They are not that hard to change. Usually a nut or 2 screws in the temp bulb area at the burner end and a nut that threads into the control valve.
Make sure before you install the new one that the area where it mates to the gas valve is clean. Should be about a 20 min job including clean up with replacement parts in hand.

Most likely it's time to replace the thermocouple, the safety device that makes sure the pilot is lit. New thermocouples are cheap and you can find them at most hardware stores and the big-box places (Home Depot, etc.)
Here is a site with basic information to get you going.

try cleaning the top of the pilot light jet if you can get to with small brush then blow it clean with a compressor.

Typically, if you have replaced the thermocoupling and are still experiencing problems, it means the master control valve is bad. It also may be a venting problem, which I would not rule out. If you call the manufacturer with model and serial number, they will be able to help you better diagnose your problem.
