That is a millivolt gas valve. It uses a pilot generator as a pilot safety plus the generator produces the power to operate the heater's solenoid inside the gas valve. If the pilot is going out after 10 minutes I suggest the generator is getting weak. These pilot generators are not cheap. Because they function as the main power that operates that gas valve, they are not like an ordinary thermocouple.
When these get weak they shut down as the thermostat begins to cycle on and off.
