Several times in the past month while driving on the highway the truck has stalled followed by a loud thud from the transmission - all of the dash lights come on, and the vehicle restarts, but the transmission does not engage for several seconds and only one gear is available until the vehicle is shut off and restarted. Also have had some problems starting the vehicle since the first 2 occurrences on the highway. Replacing the ipdm as this is a known issue with the vehicle. This is a very unsafe problem that needs to be corrected immediately.
