Potterton Prima F boiler works for a few minutes and then turns off?

My 10 year old Potterton Prima F wall mounted boiler will try and work, the pilot light is lit and ignites the boiler for a few minutes and then it turns off. Have tried to reset which will sometimes ignite the boiler but again only for a few minutes, maybe a bit longer if I'm lucky.

All the previous answers are possible but the most likely answer is as detailed at this website. http://kaijaks.co.uk/blog/nick/2008/02/10/dodgy-old-boiler

The explanation is very good.

Try replacing the thermocouple which you can buy from B&Q for around a five pounds

Pilot light seems to be on all the time and tries to do its job but the boiler keeps switching off
