Thanks all. I did two things that may have cured the issue.
- the iFi Micro USB 3 has a grounding switch. Manual says to defeat it and cut the ground. Well, instead I decided to engage the ground switch
- I plugged one of my LPS units in a different BPT conditioner outlet
It has not happened since. Hope this is it!
