I called them and they of course said that is was most likely something else...."there is probably something wrong with something feeding the box."

I can't think of anything else that would instantly kill the engine while driving for over an hour on the freeway and then start right back up like nothing has ever happened after a few minutes.

I did a search on the Permatune and there seems to be people that are OK with them such as John Walker while others think they aren't all that great.
