While driving my 2002 ford sport trac at about 40 mph,engine shut off without any warning,just a shaking feeling,then completely shut off,while in motion. very dangerous situation! no check engine light came on and no codes were present. i was able to get out of traffic and avoid being hit. had to crank for about half a minute and it restarted. have driven on a daily basis about 200 miles since and problem has not recurred as of yet.vehicle is well maintained and up to date on filters,etc... *tr
