ZHP Mafia Family,
Been awol for awhile... car has been running great!
Until a little glitch this morning...
Car was up to temp, ran some errands. Cut out ONCE right before a pulled into a store... thought "I need to put a can of seafoam in the tank" as I just filled up with 91 non-eth yesterday...
Then, after that, the problem started to be more frequent, see this vid:

Cuts out for 1 sec, (rpms drop to 0, battery light comes on) then comes right back up... very annoying as power cuts in that 1 sec. Car doesn't die (I don't need to restart). Happens load or no load, doesn't matter. Really picked up about a mile from work... was able to limp into work. I would time my acceleration right after a cut.
What I've checked: Battery terminals tight in trunk, serpentine belt good, no visible issues in engine bay.
Searched some here and e46fanatics (replied to a thread there), and 3 things seem to be possible causes:
1. Crank sensor
2. Ignition Switch
3. Alarm issues (less likely, stock USDM car)
Thoughts?? I do have a hardwired Valentine1, but other than that, no other electrical add ons.
From what I can tell, it DOESN'T kill full accessories.. (need to check if radio cuts) but my V1 seemed to stay on. (chirping in vid, but unrelated)
