I have a Weil McLain Eg-75 steam boiler that has recently started shutting off. Here is what happens:

The boiler will stop functioning.

I then go down to the boiler, and the pilot light will be off. I then blow it down by releasing a ton of water (seems like there may be too much water?), I will have to release water for around 5 minutes until the McDonnell Miller Water Feeder is triggered, then water will be fed back in until it stops (there is substantially less water going in than I released).

I then relight the pilot light.

After a couple hours the boiler will spontaneously turn back on. The boiler will operate for another 2-4 days until I have to repeat the process. Any idea what the problem may be?
