Land Rover Repair: Frustrated!!!, engine parameters, convinience

Question
John, my 96' Range Rover, 4.6 SE with SE miles was a dream machine until it started to lose power and finally, it stalled. After retrieving the computer codes, it showed a faulty crank positioning sensor. It was replaced and it did not solve the problem. After checking the fuel pressure, it had low 20s. The fuel pump was replaced and the pressure was back to 36. It started fine and when it warms up, the same problem occurs. It seem the fuel ratio gets out of whack. I'm in desperate need and need your help/suggestions at your earliest convinience.  Thanking you in advance for your kind and prompt assistance.

Answer
Find a shop with an Autologic or T4 system.  They can watch all the engine parameters on the tester's screen and it should be apparent what's going awry when they do so.

You can chase problems like that forever in your driveway.  Proper tools just make it so much easier.
