Dodge Repair: intrepid mystery, crank sensor, 1997 dodge intrepid

Question
I HAVE A 1997 DODGE INTREPID 3.5 THAT WON'T START. WE'VE REPLACED THE CAM SENSOR, CRANK SENSOR, IGNITION COIL, AND ENGINE COMPUTER.IT'S GETTING FIRE AND THE FUEL SYSTEM HAS BEEN CHECKED. WE HOOKED IT UP TO A SCANNER AND IT GAVE CODES FOR CRANK, AND CAM SENSOR. THE CAR WILL START THEN STALL BUT WILL NOT START AGAIN UNLESS YOU CUT OFF THE SWITCH. IT ACTS LIKE IT'S BEING SHUT DOWN LIKE IT WOULD WITH A BURGLAR ALARM BUT IT HAS NO ALARM. I'M REALLY STUMPED. ANY SUGGESTIONS WILL BE GREATLY APPRECIATED.

Answer
Stumps me too, but the only suggestion I could make would be an ignition module may be faulty. Some times a scanner will not call back a code for this. I don't know too much about the Intrepids, since I haven't worked on but one or two yet. Hope this helps.
