Yeah, the PCM is picky. I noticed on mine when it did it it only took a
drop to 11.6 volts for it to start acting loopy. 11.4 volts will make
it nearly impossible to run. I could bump my battery (actually both
times) and somehow the truck would run fine again for a while. I know.

On mine it took about ten minutes to cool down before it would start.
At first it started acting like you described, where it would just
idle, but after a wile it would just plain die (speedo too). Pull over,
let it cool, and then it runs fine. Mine went from the first set of
symptoms to the worst set in about 20 miles of driving. I know that
because I was camping and it did this on the way home and took me an
hour and a half to do a 25 minutes drive. I may be way off here
(probably am) but it is something to check out.
