Truck Randomly Dies at Stops

[boy&hisdogs]

Three times now in the past few months, my engine has shut off when I pull up to a stop sign or light. The electronics stay on, and the engine doesn't run rough before it happens. It's so smooth and quiet when it happens that I don't even notice right away. One time I got a code for a bad O2 sensor but the other two times I got no codes.

Any ideas?

What's your fuel pressure? Does it leak down when you turn off the key?

I had Abad EGR valve that did this to me once, even though it checked ok when I checked with a DVOM. I don't recall if I had any codes.

I swapped it into another truck with the same engine and problem went with it, do I had found my problem.

But would check other things...do you recall what your code was? These intermittent electrical problems need a scanner with live data.
