1998 Grand cherokee

Yes, but my problem came in a 1995 wrangler 4.0 liter. It is the camshaft sensor unit. Mine was in the distributor assembly. Get one I can almost garauntee that is what it is. I cannot however garauntee my spelling! Hope this helps!

change the fuel filter

you have to be careful that it is not the safety neutral switch.since stall means different things to different people,it is hard to tell exactly what is the issue.if the safety neutral switch,which is wired to the start and ignition circuits is bad,it could kill the engine.
jack up the vehicle and look for bad or shorted wires or connectors before doing anything else.
the other thing is how it behaves with no load on it. put a floor jack under the rear differential and raise it just enough for the wheels to be off the ground a couple inches.put it into reverse with no load and see if the wheels turn in 2wd mode.

If the battery does not hold a full charge the vehicle will not idle, replace the battery

Does the vehicle crank for extended period of time upon first starting? If so the fuel pump needs replacing.
