Hi, Trevor.

Sounds like the thermocouple is on its way out.  You _might_ be able
to get a few more lights out of it by redirecting the pilot flame or
increasing the gas to the pilot, but your best bet is to check the
connection from the TC to the control then replace the thermocouple.
They cost a few bucks at a local hardware store.
