A couple of long shot ideas... Have the battery load tested to make sure it is at 100%. Modern auto electrical is very sensitive and does weird things if the power supply is even a little bit off. Also, I agree it doesn't sound like a fuel supply issue, but have the fuel system pressure tested and if the fuel filter hasn't been changed in a long time, or ever (like mine) it's possible there's debris in it that's interrupting fuel flow from time to time.
