Need some help please. I have a 2006 6.0l. This started several month ago. Driving down the road truck just shuts off like you turned the key off. When it happened the first time, I thru it in neutral and restarted the truck. No problem. Did not happen again for weeks, then it happen again. Same thing, thru it in neutral started right back up, on down the road. No issues. Today, several weeks later, coming home from work, it died. I thru it in neutral, it started up. This time it died again several hundred yards down the road. It started again. This time made it about half a mile. Died again. This time would start but immediately die. Made it to a parking lot. Turned truck off. It started up, drove home about 5 miles no issue. All my voltage looks good. FICM,batteries an all. Anyone have a clue? Thanks for the help.
