Jeep will just die going down doad or will not start, had a code that read camchaft sensor replaced that still the same, now i have a code that reads injector circuit malfunction i mhave changed fuel

I am having a problem just like that now on my 2000 Jeep Grand Cherokee Laredo. It started when i was leaving work and as I started to back out of my parking spot i got half way out and my jeep just died. All my lights still worked; radio everything. I got a couple friends to help push it back in the spot. I could not get it to start again so, I just popped the hood and started to look at my battery cables to see if they are corroded and they were just dirty but not totally bad. I noticed that my negative battery cable was lose so i tighten it up the best i could and went to started it up and it started with no problems. I started to drive it home and got about 3 miles away from home and it died again, and again the lights were still on,radio on also i did not see any warning lights on the dash (service lights, check engine lights...) so i popped the hood again loosed my cables cleaned them more and put them back on and drove it home know problems. That weekend i went out and bought some battery terminal cleaner and scrubbed the cables till they looked new. Well I went to check it out and started it up. and it started up again no problems no warning lights i drove about 50 yards away from the house and it died again. I dont know what to do, I dont know much at all about fixing anything on a car. Also right after it dies i tried strarting up and the engine will turn over but it will not fire. I have had my battery checked and its good. I check to see if my alternator was working so i check voltage at my battery to see if i was getting 14 volts and i was, also I notice after it dies my battery voltage indicator drops to about 10 volts or so. I know this is a long message but any help would be much appreciated. I am also good reading- wiring schematics so if i could get some i would appreciate it or service manuals anything. Thank you

On some cam sensors they must be re-calibrated with a scan tool. that sensor also controls injector timing through the ecm. If after you get that squared away, the vehicle returns to normal but still includes the shutting off thing, check the crank sensor after the engine dies and see if it checks out (no resistance between b&c terminals of the sensor)
