My 96 3500 dully dies when you get it up to operating temp. until then it runs fine and it will just randomly shut off driving not miss nothing.

Going to need more info here...

Does it die every time it warms up? Is it immediate once the truck is up to operating temp? Have you serviced the truck recently? What shape is the fuel filter in? When it dies, will it restart easily? Can help you but this post is about as vague as it can be. You may need to invest in an OBDII scanner with live data capabilities and be prepared to rent a fuel pressure gauge.

ok so here I go. it dies anytime that its warmed up an 90 degrees outside. no its not you can drive 1 mile or 5 miles before it dies. I don't know about service records on the truck I just got it this last week off my brother. it was doing the same to him. again I have no clue on the fuel filter. and when it dies no it has to sit till its cool again before it will restart. I have a new cap and rotor I'm gonna put on it tonight. and the wiring in this thing is a mess extion cord running the back lights. so I'm gonna be redoing all that in the near future. only reason I bought the truck is I only gave 150 for the truck lol.
