Latest update:

Now we think there might be a chance that the house power is messed up. Happened to witness the house power flicker off then on. Talked with the power company and they are "investigating". It was very brief and I wouldn't have noticed it except I happend to be home and the lights turned off then on. It happend twice over two days so I'm crossing my fingers that it's not the electronics on the pool pilot. Power company said they will have a report on the problem competed within 5 days. So, we will wait and see....
