I would tell the truth all right.

Then explain: The PS is a wonderful unit that when maintained properly will offer the user a great product. As with all PS XXX. A simple reboot once a month keeps the unit refreshed and trouble free.
I hope you enjoy the product as I have.
This is honest and shows you are truthful and are selling a good, serviceable product. If anyone questions the practice, refer them to your information and where you got it. Note that several others like yourself looked for a solution and found one.
What you are doing is a very common practice with any processor, the issue I’ve found it’s not a single processor with an issue. It’s normally some sub processor not playing well with others. You need to flush and start over so to speak.. Buss issues are "timing and joining the different buss systems". Unless they are designed to reboot, or pass the work to a working back-up. They freeze up.
Side Note:
If it was a Cann Buss it would throw up a code and show which sub/processor/unit had a wiring issue, buffer boo boo or an actual processor problem. Can Buss uses, a null process to check the hot/cold wiring error (kinda like XLR), checks the data wires, checks the sensor circuits, checks sensors, checks the grounds. It’s not inexpensive but redundancy need to be built in. NASA, kind of thinking.
The fail safe with any computer is to cold boot. 5 minutes for every processor up to 15 minutes. Same with any computer, remove the power supply and backup power supply. Unplug and wait!!! Hundreds of times with equipment, trained VETS would not wait long enough.. 100s They always thought I was slow, I was patient. :-)
Skunk at the chicken coop, CRAP!!!
