I have a 2002 GMC Sierra 2500hd with the 8. 1l engine that is exhibiting the exact same symptoms that led to the recall of the 2001 model. (NHTSA # 07v521000). One minute I'll be driving down the freeway and the next minute the engine will stop running. This has happened numerous times. Sometimes it'll restart before it comes to a stop. Sometimes it will take several minutes after it's come to a stop. I've researched it on-line, and it would appear that this problem is not restricted to the 2001 models. The date I've listed is when I first remember it happening. It's very intermittent. It's getting worse.
