You should feel good that you got that far on your own - wait far would imply
that you made progress - actually I think you are making progress because you
can safely rule some things out (that you tested already).
I personally have had a bad MAP sensor that never flagged a MIL (was always
within spec even tho it stayed at 3V constantly!) and we here of things like
the crankshaft sensor and things that can go bad without the computer knowing.
It's pretty obvious that ma mopar was mostly concerned with emissions when
designing the PCM as its relatively dumb when it comes to troubleshooting.
Keep your chin up and march on - the satisfaction of finding it will only be
greater.
I do like Bernd's idea of a partially clogged fuel pump inlet sock. I would
put a fuel pressure tester on my test port with enough line to run up to the
windshield - you can use the wiper to hold it during a test drive. Now you can
watch it full time. It should stay pegged to at least 49.5psi (+/- 5psi) if I
remember correctly. Another option if you don't already have a gauge is to buy
an Intellitronix fuel pressure guage with remote sending unit (in cab
compatible) - it has a preset pressure you can set and a light will come on if
it ever gets above/below that point. They start at a measly $40. This will
allow you to check that sock without pulling the tank and pump.
On the other hand - if you have lots of miles - I would want to look at that
sock anyway.
Good luck.
