Dodge Diesel - Diesel Truck Resource Forums - my truck shut off ..... ??

heres what happened ......... i went out this morning to start my truck and realized i hadnt plugged it in overnite. it was 7 degrees ( i know thats almost shorts and t shirt weather for some of you guys ) so i cycled the grids 3 times and popped her off. she ran rough at 1st and really smoked but then calmed down. i let it warm up about 10 - 15 min then drove about 10 miles and shut her off for about an hour. then i drove again for id say a good 1/2 hour or 45 min..after this last 30- 45 min drive i pulled into my parents driveway and it just off ...like it ran out of fuel ( kind of like i turned the key off ). i tried to restart and while holding or pumping the throttle it started then shut off again. i thought maybe it lost prime so i got out and pumped it up and then it started again. after idleing for a good 15 min i drove around the block ( 5 miles ) and it died again, the same exact way. after getting it running again. i shut it off and drained the water seperator and primed it with the hand pump again. i also added some more howes and a bottle of fuel line antifreeze to the tank. started it and went inside my parents place to warm up and after another 15 min at idle it was still running . i drove it home ( 7 or 8 miles ) and it seems fine. any idea what happened ??? did the fuel line antifreeze do the trick ??? help me guys this is my 1st cold weather issue with a diesel. i need it running tomorrow because my KDP has a date with the executioner.. thanks guys and sorry about the long post just wanted you to have all the info.....thanks again, scott
