I had this happen at TRR14 following a couple trucks, very dusty. It hesitated, went a couple turns and died. Everything looked okay, had new air filter still clean and no tune. Started truck again and it ran several laps all weekend. WTF ?

You all need to look for extra connecting rod bolts in your oil pans, that's probably it.

Ok, a question since it sound like it was my tune and just recently changed. I haven't driven a 100 miles on it yet since I went back to stock and done with the dealer. Want to put the tune back on it. Is there any issue changing tunes too soon between changes?

Not at all, just do the battery disconnect for 15 to 20 minutes.
This will insure that the PCM will start a new drive cycle with nothing in KAM or wide-band tables.

I changed tunes from 5 Star (87 Perf, 87 Eco, 93 Perf) and SVC and back to stock numerous times but it always been 500+ miles apart. I have never disconnected the battery between any tune or stock. Why?
Or do I only do that because I want to switch sooner than 100 miles?

It's the recommend procedure, I've changed often as well, sometimes you may run into a glitch, like ambient temp not reading correctly or just other odd thing going on.
It's just good practice.

Also check the SCT software update they had an update a couple of weeks ago. Well at least for my X4

Another n00b question, when the battery is disconnected for that long, do you loose anything? As in radio stations, nav destinations, etc?

Nope, the Nav/Radio Head Unit has it's own Non destructive Rom.

I'd like to know that too for future references (Just in case)

Edit: thanks @MTF
