well its not my truck but my buddy has an 07 dodge with the quadzilla x2 and a superchips stacked. here lately it keeps dying. he will be driving down the road and the D*** thing dies. if you turn the key all the way off then back on the truck will then start back up. any one have any suggestions? they would be greatly appreciated thanks

 

Mine has done that twice, and both times it was due to a damaged wire harness. Have your buddy check his out. Start by making sure the connections are still secure.

 

This has also happend to me - twice-.
Last night read about the section of the harness that goes over the a/c plumbing near the bottom of the oil filter, look up at the begining of the forum there is a section to look for a shorted wire, good pics and explanation.
Took me 45 minutes to rectify I hope!, this includes a trip to Napa.

 

My quadzilla harness was doing that to me, just cut out without warning. I had the standard box reflashed and then the harness started acting up. The new harness cured the problem....Try removing the quad setup for a while...
