Sounds like the Solenoid coil is dropping out - a common fault which sods law says will happen after the boiler has been serviced!

I think this depends on how thoroughly the service was done - was all of the soot removed? Did he take the baffles out of the boiler casing and clean them?
He should have renewed the nozzle, ideally, and set the pump pressure to 140 psi. He should then have done a smoke test, followed by a flue gas analysis to see how to set the air door. Does the burner reignite after lockout?
