Jeep cut out.

My 2001 Jeep Grand Cherokee Laredo will cut out randomly while driving. It only does it while its in drive. It feels like a fuel problem but the fuel pump kicks on and i've replaced the fuel filter, screen on the fuel pump, neutral switch, coil pack strip, map sensor, spark plugs, and i've checked battery terminal connections. I'm running out of ideas and would love to hear some more. Like I said, it only cuts out while in drive and have pressure on the gas pedal. You can put it in neutral and rev it to the moon and it does fine. It doesn't cut out all the time either. But it is annoying.

It cuts out like it's going to run out of gas or it actually loses power?
If it feels like it's running out of gas, trace all your fuel lines.
If it feels like power, have fun. Trace wires, grounds, connections, wire harnesses and so on.

Do this process to check for what code it is throwing:

Turn the ignition key until the digital odometer displays, repeat three times in succession and then back to "On" (On/Off, On/Off, On/Off, On). At the fourth "On" the odometer will be replaced with codes. If no codes are present then "Done" will appear.

Once you get the code, post it here

Sounds like P0320...crankshaft positioning sensor. Very common in WJ's.

If so, look at NELLY246's thread, 'engine cuts out while driving.' I'd be willing to bet this is your issue, and I and others helped him diagnose and fix it himself.
