Going down the road my truck just dies out
 

I have an 03 2500 and when im going down the road it just cuts out with no warning at all more so when you let off like going down hill or at a stop sign. It almost seems like it just runs out of fuel but other then that it runs great. What could this be and how would i tell? Thanks

sounds like a sensor like a crank possitioning sensor we have an international that did thats what it was but im not a mechanic so im just throwin that out there

hmmmnnnnnn
