Electronic pilot & boiler won't stay lit

Burnham P-205-WNI. (electronic pilot, NO thermocouple). Pilot will light but then goes back out. If I unplug the white wire to the 24V spade at the control box and wait 2-3 min. When I plug it back in the pilot will light and the furnace will light for about 10-15 seconds, then I hear the gas valve shut & all flames go out and it goes back to pilot light kicking on & off. After I do the little un-plug the white wire trick 2 or 3 times the furnace will light and stay lit.

I think the first thing you might want to try is cleaning the 'flame rod' and making sure that the pilot flame engulfs it. The 'flame rod' is what detects the presence of flame. I believe that your control is called a 'continuous retry' model which will keep trying the pilot forever.

What color is the pilot flame?

Do you have the manual for your boiler? If not, go online and find and download a copy.
