Sterling oil burner with intermittent lock out

[grill]

Hi guys,

Was recently called out to a Sterling oil burner (cant remeber model name) which locks out intermittently.

The burner can run away merryily for hours, come on and off with the thermostat but then sometimes just locks out. Hit the reset button and away it goes again for another while.

He said the burner has run now for 3 days with no problem but locked out again tonight.

Is this a control box on its way out???

Any thoughts would be most welcome
