Unhappy Help!!!! p1682 code has me stumped.

Ok i just bought back my 02 Dakota SLT with 4.7/auto. I have tried everything I know to solve the problem. When I first start the truck everything is fine, after a few miles the "check gages" light comes on and the battery gage drops to nothing. I have replaced the alternator and tried 2 different batteries. I had the batteries and alternator load tested and they passed. If I turn the truck off and back on while driving the gage returns to normal sometimes, and other times it returns lower. Sometimes while driving everything seems normal and the gage never drops. Somebody help, I was told it could be the PCM but i want to eliminate everything else before I spend the near $300 for it. Any help would be greatly appreciated.
