This is probably due to a faulty thermocouple. The thermocouple generates a small voltage when hot that is used as a security device that keeps the gas flowing to the pilot. These are relatively inexpensive (UK about �18).
You can check if this is the problem by measuring the voltage on the wires coming back from the pilot. When you have the red switch depressed, check the voltage (should be about 30mV). If there's no voltage, then change the thermocouple.
The thermocouple will generate up to 50mV in a pilot flame. If it falls below 20mV it should kill the fuel source. It may take a few minutes to generate enough voltage in order to keep the pilot lit, so you may have to depress the button for a minute or more. This would be typical if your unit has been off for an extended period of time.

I cannot find a current listing for Teledyne Laars. As far as I can tell, Teledyne and Laars separated, Laars joined up with Waterpik and then got reorganized under Jandy. www.jandy.com now has the Laars Lite2 line of pool heaters with the LG model almost identical to the Teledyne Laars LLG. You can access the manual at http://www.jandy.com/pdfs/H02359-.pdf . Jandy also has a parts list for older discontinued models.
