Engine dies and no codes.

I had my truck die on the interstate last week. Thought it was classic CPS problem even though I had the CPS recall done. I get it to the shop and he replaces CPS (it had read a code for CPS) and truck fires right up. He runs it down the road and truck dies with scan tool in truck. No codes.

Any ideas. Had injector work done and have run tranny fluid through three tanks to clean up others. Truck had plenty of power so I don't see that being an issue. Truck just dies for no apparent reason.

Mechanic has my truck and cannot find a cause. Please help me lead him.

Does it die all of a sudden? Or does the idle get rougher, and than it dies?
Does it die instantly? Or does the truck warm up, and than die?
Does it always die completely? Or can you hear it start to go, and then stop it?

Died instantly. Shuddered for about 1 second and then the engine just stopped. Wouldn't start back up. SHe was very warm, city traffic for about 15 minutes and then 30 minutes of interstate driving at 90+ degrees.

As far as mechanic testing her now, I do not know but same thing, she just dies and doesn't trip a code one.

Yea, dirty oil or low oil can cause similar symptoms, but its USUALLY not that simple .

Have you had your EGR valve cleaned lately? I had mine get stuck open and didn't throw a code. The engine died and wouldn't start. I removed the valve, cleaned it and have not had any problems since.
