It has a sensor that shuts the gas flow off if there is no heat. This is a saftety in case the flame goes out. Often the sensor is not placed close enough to the flame to get hot enough, or it's bad. I'd try finding the sensor and budging it a little closer to the flame, and it should stay on, otherwise, it will need replaced.
