Another couple of (possibly) random data points:
I just read the "Disconnected battery, reset procedure" thread and I MAY have unintentionally done this both times before it restarted. Sometimes my car won't just go into reverse or drive and I'll have to wiggle the shifter a little bit to get it to shift. Very rare. So I could have possibly shifted through the gears thinking the sensor that tells the ECU the trans is in P before it will start was spotty.
Second: I may just have the original battery. If I don't, I know the battery is at least 6 years old as I bought the car in 2012 and I've never changed it. I haven't been having issues with it, but I have run it dead twice and when this happened today I was reminded of all kinds of ECU juju that happens to my Mercedes ML if the battery isn't up to snuff.
