2006 Cadillac DTS

Bought my DTS with 46,000 miles, one year ago. I have driven 31,000 miles since. Once in a while, maybe once a month, at 65 or 70 mph it will just hicup once and keep going. Just one quick miss. About 6 or 8 times in a year it has just died going 30mph or pulling into a driveway or up to stop sign. It does not sputter or miss, simply just dies instantly. So far it has always started right back up. The only code it has ever shown, was mass air flow sensor twice. It looks ok and I did clean it. Any ideas or experience with this problem? Thanks bjkitte

Those are the hardest problems to troubleshoot. They pass so quickly and leave little to no evidence behind.

It is probably a connection somewhere that under just the right circumstances, breaks for just a moment. Good luck finding it.
