After about a month of pulling my hair out trying to find the cause of this elusive problem, my brother was working on it with me one night and while I was starting the car, he noticed a spark under the battery tray...
Turns out it was a loose/bad ground connection. We took it off, sanded the metal and put it back on. Prob hasn't come back since...
Good luck!
