My 2001 Jeep Grand Cherokee Laredo inline 6 4x4 runs perfectly fine until sometimes it cranks but doesn't start. The only way we can get it started again, is to disconnect the positive terminal from the battery​. (I'm not sure if this is related but I have a system hooked up and now I hear more feedback since this problem started happening)

It may be the security is screwing up which is kind of unusual like that. try a reset and then have a mechanic scan for codes it could be a crank sensor connection as well. also if it is a 4.0l they seem to wear the wiring harness at rear stud of head and cause similar problems which if that is the case then it needs fixing there and rerouting.
