lead continuity on flame sensor may not be enough, is it correctly positioned and cleaned? sounds like a flame
rectification problem........possibly pcb related, but would be changing the rectification probe first (and also making sure there was good earthing on the boiler)
try disconeccting the rectification probe and running the boiler, see if the problem is the same one.
