Pilot Light will not remain on

[Paulden]

Help,
I have a Potterton Suprima 80 central heating/hot water boiler (about 7 years old), and periodically (perhaps once per 10 days), the boiler stops and it is VERY difficult to restart - after pressing the start button, it will fire for about 5 seconds then cuts out (it then retries 2 or 3 times and then cuts out completely). Typically it will take MANY attempts (perhaps spread over a day or two), before it will stay on.
Then it works fine for another 10 days or so !
Any ideas ?

COuld be a standard ignition problem, dirty pilot jet sort of thing, or the usual. "Usual" would mean new pcb required. Needs a corgi to diagnose. If you need a pcb let me know.
