It's probably the thermo-coupler. This is a device that senses when a pilot light is lit and burning by sensing heat. Only when it senses the burning pilot light will it allow the valve to open and let gas flow to the main burners. It also cuts off the gas supply to the pilot unless you manually over-ride it by using the "light pilot" button.

The thermo-coupler is a small cigar shaped device about 2" long and it's mounted right above the pilot light.

Sometimes, you can simply clean off the thermo-coupler with sand paper and it will work again. I'd try this first. If that doesn't work, then follow the thin copper tubing from the back of the thermo-coupler to where it mounts on the gas regulator. Unscrew the nut and release the entire system and replace with a new one.

It's probably the thermocouple that's bad... It's easy to replace and thankfully not very costly, although you might have to go to a place dedicated to appliance parts to find it.

The thermocouple looks like a piece of bare copper wire that will connect near the pilot flame. It tells the stove when the pilot is lit to be sure that the burners don't come on if it's not. The tip of the thermocouple is placed directly in the pilot flame. Trace it back to where it connects inside the control panel to remove it.

Take it with you to an Appliance parts store along with the make and model of your stove. They should be able to sell you one. Just reinstall, using the opposite sequence of that which you used to remove it.
