The conclusion...

Finally got a good loaner from them, a 4 door HEMI Ram. Nice truck, KILLER ENGINE, but after driving it, I am glad I opted for the Dakota (but only if they would put that engine in a Dak, though).

Back to my truck...the dealer had to disconnect the Neg. battery cable to kill the alarm and lost all codes. After her did that, the truck started and ran fine. Tested the battery and inspected wiring, but he could not duplicate the problem, so the truck is home now, waiting to see if it happens again...

Some glitch somewhere, or maybe the evil gnomes
