Issue with bolier start

Cerberus

I recently purchased a home that has 1994 Burnham Steam boiler that worked fine until the last month...



Under the normal operation you can hear click as the cycle begins, pilot flame comes on, then ignition begins, usually 10 sparks,  after which gas valve opens as heat boiler kicks in... Recently boiler randomly stalls... thermostat calls for the heat, pilot flame comes "ON", ignitor (electrode/flame sensor shown in picture) only sparks 3 times before it goes silent after which loop ends... thus no heat... it might takes minutes or hours for heat to kick back in by itself  or another solution is to manually restart which can also take few tries.



I am trying to figure out whats the problem, module or bad electrode?



Any help would be great,



Thanks a lot
