I have replaced Crankshaft, Camshaft and Throttle position sensors on 2001 Grand Cherokee 4.0 engine, but it still will not start after engine is warmed up. I don't know what else to do. I give up. If it were my vehicle I would just shoot it, but it belongs to a friend.

I dont want to sound like an idiot, but did you reset ECU/PCM?? I replaced my TPS once with no effect. Once I reset the ECU everything worked great. Forgive me if I sound like a noob.
What goes down must come up

Very common for your issue. The pcm signal out to fire the coil pack goes away. The ckp and cmp signals in are good. I would replace the PCM. You need a good scanner to flash the vin to the new pcm. Our shop charges $20 if you install the pcm. Usaully the jeep will start and run, but the MIL will be on.
