Jeep Repair: Stalling problems, fuel pressure gauge, crank sensor

Question
My 98 JGC 4.0 6 cyl is stalling while doing 75mph on the freeway.
I wait a couple min and she starts back up, once the engine is warm she runs great.
I hooked her up to a computer and got
P0351 – Ignition coil #1 primary circuit … Replaced
P0320 – No crank reference signal at PCM … Replaced crank sensor
P0302 – Cylinder #2 misfire…

I changed the distributor wires, cap and spark plugs
Cleaned the throttle body and got a oil change.

What could the culprit be?

Answer
I would suspect that the either the fuel pump is failing or that the filter/screen on the fuel pump is obstructed. This type of failure will leave no DTC's and is somewhat difficult to diagnose. Either way you're looking at replacing the pump assembly as the filter is not available separately. To verify this suspicion, if you have access to a fuel pressure gauge with a long hose, attach it to the fuel pressure port on the fuel rail and monitor the pressure when the vehicle stalls.
