We'll replaced the fuel pump with a Bosch pump this morning just to see and peace of mind, my fuel pressure is now at 50psi at start up and 49-48 running and hold at 40psi when the engine is turned off... that's great but still having cut out and dying issues... about to roll it into a lake!!!

After a long grueling battle with my jeep the problem is finally fixed, after ripping my hair out several times I finally pulled the ignition cool of and tested the resistance out of the vehicle and it was way out of the parameters... replaced it and it runs great... so you might be wondering why I didn't try this before... I have a MSD box on the jeep and while it was hooked up the coil was testing good once the MSD box was by passed it tested bad. The only thing I can figure is the MSD was forcing the bad coil to work... maybe that sounds stupid I'm not sure if that's possible or not but the end result is my jeep is back on the road. Thank you to all that was nice enough to take a few min out of your day to read and post up to help me figure out this extremely annoying issue.
