Do you get a chime, your engine shuts off and then comes back on? Does your tack start to head to 0? Can't get an error code? It's your MDS system failing. Do a MSD delete with your programer and your problem is solved. It has cost me 1.5 mpg in city driving. I have a tune from HHP, a 87MM TB, and a MOPAR Performance TCM, with a heavy foot.
I spent weeks doing experiments with mine, different tunes, no tune, all had the problem until I did a MDS delete. 87,871 miles, 2006 R/T with every thing. And a REAL RAM AIR hood.

Good to know, I wonder how many others have had MDS failing issues. Prolly would be a good thing for dodge to know since they are putting MDS in the 6.4L
