02 duramax

[hawkeye43]

I have a 02 duramax with 347012 miles. When I drive on a wash board road or across a rough field, sometimes it just quits. You can put into N or Park and it will start right up. Sometimes it will go for a week before it acts up or it will do it 4 or 5 times a day. I have had into the shop many times and no one can find the problem with it. Anyone have any thoughts on this???

Bad fuel filter?

Just had same type of condition on one of my work trucks, every time the guy would take a sharp turn it would quit. So, possible ideas are check to see if it has a crank case sensor. If does maybe going bad when oil sloshes on it. Same with water level sensor possibly.

CPS........cam position sensor. Tell shop to check it.

Maybe a long-shot but sounds like possibly a harness problem. Let it idle and move and wiggle any wiring harnesses and/or connectors that you can get at and see if it dies.

Yep, another good idea!
