Welcome to DieselPlace

Please list any mods on your LB7

Checked for any codes?
Any recent work done?

Mine did that to me years ago.(I have a 2004 LB7) It would tend to shut down going around sharp curves and run rough on straight roads. Tuned out to be the tone ring on the end of the cam shaft was missing two bolts and the 3rd one was loose. This may or may not be your problem, but it was mine.
