Buick LaCrosse Stalling

edmunds0628

I've read hundreds of entries regarding stalling issues with LaCrosse and other Buick models. My 2008 LaCrosse will intermittently shutoff while driving down the road. I've had the factory recall key spacer installed, had the ignition switch replaced, had the ignition relay replaced, even replaced the crankcase sensor. Now I hear that the fuse block under the rear seat may be the problem. Can anyone shed some light on this headache?
