2002 Dodge Dakota Quad Cab Sport w/4.7L engine

Question

Problem:  While driving the truck will shutter and try to shut down.  Gauges will drop and then immediately come back.  Code P0725 came up and both the camshaft & crank shaft sensors, inlcuding wiring harnesses for both, have been replaced.  Still the truck shutters and/or shuts down (this is an intermittent problem). I get no "check engine light".   Also the the ECM was replaced a year ago.  HELP!!!
