I bought a 2004 Z71 on May 15th. Twice I've been driving for a long period of time (3 hours+) and have blown the PCM1 fuse after going over some rolling bumps in the road. This kills the engine. Fortunately both times I've been in a rural area with straight roads, so I was able to pull over with out any issue. Once I replace the fuse, the truck fires back up with no problems. The first time the dealer could not duplicate the condition and said that they couldn't find anything wrong. As for the second time, I dropped it of this morning, so the jury is still out. Anyone out there have a similar problem?

Thanks.
