ok, your unit must be propane. look on the back where the propane line feeds the nozzle. there should be a very small copper line with two spade connectors on it. this is your millivolt generator line. with a flame at the nozzle the generator makes a very small electrical current which feeds to the main valve and keeps it open. take a piece of wire and jumper these two spade connections together and try lighting the unit again. if it stays on, the hi limit is shot. you can get by with the connections jumped out, you just don't have the safety margin if it were connected. IF with the spade connections jumped out the unit still shuts off, the generator tube needs to be changed.

crappy pilot flame (not properly heating the thermocouple), bad thermocouple, thermocouple loose where it screws into the pilot safety valve, bad safety valve magnet.
One or more of those is the problem.
Oh...there is also a saftey switch...in case it tips over. It will also cause the pilot to not stay lit (if the switch or wires that go to i are faulty)
