Intermittent Stalling/Dying While Otherwise Driving Fine...Restarts, Drives, Randomly Dies Again.

Interesting.  I used up all my brake cleaner spray recently but will pick up a new can and give that a try.

Spray some near the header while at it, particularly near the back of the engine.

You can also just use water while the engine is running to find a small vacuum leak. The rpm will dip while the water is being pulled in (temporarily stopping the leak) and going through the engine, sometimes it makes noises. No harm in doing it either, it’s no worse than driving in the rain. 
 

Smoke testing works by pushing pressurized smoke into the system and seeing where it leaks from. Potentially you could do similar with soapy water, but I’ve never attempted it.
