2000 xj Driving me crazy!
Ok, I have a 2000 rhd xj, use it on a mail route. 2 weeks ago, just cut off while leaving a mail box. CEL blinked a few times, then jeep shut off, would not crank back. Blew a fuse for coil pack, replaced coil pack, no better. Have since changed CPS, cam sensor, even changed computer,still stalling out. It will crank now, but wont stay running, might run 30 mins, might cut off before you can get it in gear! When you come to a stop it will die if you dont keep gas to it. Checked wiring, didnt really see anything wrong. I think I have had the problem with injrctor vapor lock before when hot. Could this maybe have happened and blew the fuse for the coil pack? This was the first problem. Please help, need to get this jeep running! Wondered about new injectors, o2 sensors?

That's usually a fuel delivery problem. Fuel pump, filter, pressure regulator, gunked up throttle body, stuck IAC, dead TPS....
I'd start by checking the fuel pressure when it's acting up and measuring the TPS output voltage while slowly opening the throttle by hand. (key on, engine off, center TPS wire)
Checking for stored codes would be useful too, in fact do that first.
Coil pack fuse is probably unrelated, that's either a harness issue, or more likely a failing coil in the pack with an intermittent winding short.
