What would cause my truck to die? Sart it up when its cold and it will run fine then after ten mins. or so of it running it will start to miss a little then die. Then when i go to start it again after it dies it will crank for a while the finally fire, but only runs for about 30 seconds the dies. Took the feed line to the cp3 off and it has plenty of fuel running to it. Anyone got any ideas?
