Possible problem with the thermocouple. Look at the pilot light when it is lit; there should be a small probe-like piece mounted with it's tip in the flame. Make sure the pilot light flame is hitting the thermocouple. The thermocouple itself could be bad.

Must be a older unit if it uses a standing pilot. Why don't you be a good grandbaby and have them a nice new gas furnace installed for the holidays?
