Most newish vehicles won't start, or even crank, when the voltage gets below a certain point. So basically it starts fine at 12.3 volts, but the computer says "No Way" at 12.2 volts.
I'd be checking the alternator, and/or starter. What was the voltage when the truck wouldn't start? I'm sure it wasn't "stone cold dead", you did check the voltage didn't you?
Actually, I didn't check the voltage. I didn't think the no load voltage said much about a battery---but maybe it does. Sure acted to me as though the computer just said not enough voltage and shut things down.
