Mend Vaillant GB221H Going Ignite

Vaillant GB221H pilot flame keeps going out?

The pilot flame on the boiler keeps going out without warning? I am able to restart the pilot flame, & it will continue to ignite the boiler to give hot water & central heating, but intermittently goes out? Any ideas on what to check?
