I have a 2005 LT with 285,000 miles. It intermittently stalls/turns off. Have had 2 dealers look at it. Both say they did not find any codes. They have cleaned the throttle body 3 times, replaced crankcase position sensor, replaced fuse block in engine compartment. Nothing has worked. Appreciate any advice.

 

Any luck solving this issue? Sounds similiar in ways to an issue I am having. Thanks for any info!
