Is there something in the software of my 02 that will cause it to shut itself off after idleing for a period of time? It has done this a number of times and upon restart all is fine with no SES light or any other indicators. Did it once at a traffic light but mostly stopped in nuetral.

never seen anything for that, does it do it with out boxes on ? Are you running filtration?

Seems to do it only on a power level. Checked it with a Tech 2 yesterday and had no stored codes. Dealer replaced VA box with a new one and it drives like a different truck. Hopefully that was the problem. I have a Nicktane filter setup also. Thanks for the help.
