2001 2500HD with 8.1 stalling

I have a 2001 2500 HD with the 8.1L, It sometimes will die at low idle or at a stop. When I try to start it back it will spin over and run the battery down. Also sometimes after it set's over night it will spin over and then start. I have replaced the fuel pump and filter.

Have you checked for spark? I'm wondering if a coil or relay is faulting when/after it gets heated up. If you've changed fuel pump and filter that should be enough to rule that out. How often does it happen?

Replaced battery, it was bad, it still stalls, now it will do it going down the road. stalled twice in about a 10 min. span.

Try the crankshaft position sensor. My 2500 did the same thing, replaced this part, no problems since. Good luck!
