Alpha cb24 combi boiler keeps switching itself off?

Alpha cb24 combi boiler intermittently keeps switching itself off. Have cover with hydro & they have been coming out since end of nov they keep replacing parts but nothing seems to help has anyone else had the same problem? They have already replaced primary & secondary sensor, overheat switch, pcb & most recently flow switch.
