96 ZJ 4.0 not starting. Lots of new parts!

Hey guys, I have a '96 Grand Cherokee Laredo 4x4 4.0 with 278k on it. All of a sudden it won't start. It will turn over fine but won't start. Recently before it not starting at all, it would randomly lose acceleration for several seconds (all gauges drop) then kick back in like normal. Here are the new parts I have recently replaced/repaired since the issue.

In the last 2 months:

new fuel pump
new fuel filter
new #1 fuel injector
new distributor
new cap
new rotor button
new ignition coil
new plugs
new wires
new throttle position sensor
new MAP sensor
new oil pan gasket
new battery
tested and cleaned the IAC valve
cleaned throttle body

In the last 2 to 3 years:

Fuel pump (yes, another one)
fuel filter
water pump
a/c compressor clutch
Crankshaft Position Sensor
rotor button
windshield reservoir and motors
valve cover gasket

Is your Crank Sensor Mopar brand? If not, then it could be the culprit.

Ended up being the infamous harness wiggle on the PCM. Looks like it's about time to repair it or replace it. I did get it running though.
