Also understanding where the unsuccessful ignition and/or loss of flame happens in the operation sequence may help.

@L_I-John
You don't throw away a perfectly good boiler because it won't run. If the technicians can't find the problem its because they haven't looked.
Check "find a contractor" on this site
And post your location we may know someone that can help.
Are you on Long Island?

Also if the gas valve seems to randomly close or just not open, The 120V section of the Argus PHC794-S1 control board could have a failing solder joint and/or relay.
