Have to reset boiler with circuit breaker

Hey all, looking for some guidance here, I have a boiler system with circulators, and a ss-1 powervent, Oil company has been here 6 times now and cannot figure out the issue, they have replaced the power vent pc board, cleaned the vacuum switch tube, The issue is the primary control does not go off on reset, but if i shut off and back on circuit breaker the unit will fire up fine and run for days if not weeks. And no the breaker is not tripping either. Any help would be appreciated. Could it be the primary control?

    The boiler just seems to lose all power until we reset breaker.

    ...The issue is the primary control does not go off on reset...
    Can you clarify this a little better? To me that means when you push and hold the reset button the burner continues to fire, but I'm sure that's not what you mean.
    So when the burner won't fire, has the tech went from the service switch and qualified/quantified the incoming power? Checking volts, neutral, ground and hertz.

    Then move down the line and check each component for 120v.
    If so, then somewhere along the way, it should've been diagnosed properly.
    Or if you're oil company isn't charging you any more, have them keep throwing parts at it until its fixed-there's only a few more to go!

    No lights or anything from the P control or circuit board?

    Can you post some pics of the boiler from different angles about 10 feet away?

    To amplify @STEVEusaPA 's comment -- be sure the tech. checking the voltage and all does so with the circuit under load. Checking with no load will not identify an intermittent bad connection, which is one of the possibilities here.

    If your wiring is good then I would suspect the control. But, as @STEVEusaPA & @Jamie Hall said if they have been their 6 times and still don't know the answer to that then I would be looking for someone more qualified
