the weather is nice and I've been riding the bike a lot. It has not cut out once. Did it get scared that I was going to start disassembling it?
No, its just waiting to strand you in the middle of nowhere.

It's the insulation inside the splice that fails first.
Not visible unless you cut it open.
The old style units all eventually fail and strand the rider usually during a rainstorm.
They can be rewired with teflon aircraft grade wire, good for the life of the bike.
That is an aftermarket sensoer assembly. It must have replaced the original at some point.
Thanks, should I assume it’s a good one and look further for my issue with the motor cutting out
I am not sure. If truly an aftermarket system of unknown origin I have no idea what wire was used in the bundle. One might assume that "good" wire was used, but the same assumption might believe that BMW originally used "good" wire which they decidedly did not. Other wiser folks might know.
For those that like closure.
Since the HES was replaced, I went ahead and replaced the coil with a used one. Rode it about 60 miles yesterday with no issue. fingers crossed, but that seemed to be the issue. It was good I had a look at the HES as the alt belt was fraying so I replaced it while I was in there.
thanks for the advice and suggestions.
The one I took out "looked" fine , no cracks, but the issue disappeared when the coil was replaced. fingers still crossed.Look closely at the coil you took out -- sometimes, with age, the outer plastic case splits from the epoxy fill on the inside and exposes it to atmosphere. Corrosion then causes all sorts of issues. Replacing it with a used one is a totally fine way to go as long as the used one is intact.
