I've had issues with the underhood fuse blocks on them. they would run fine then just cut out and half of the fuse block would lose power. I want to say it was a faulty fuse block but I can't remember, may have been an ignition switch too. I think I have a test switch if you want to try it. Ignition switches were fairly common for other issues on them, mostly headlamps, radio and hvac turning on and off.

Does it restart immediately after it stalls? The ICM and MAF usually won't restart until they cool down for a while. I've also had a few issues with cam sensors. A cam sensor usually won't cause a stall tho.

Edit: I also had a Buick with a 3.8 that had loose terminals at the ICM connector, would run perfect for a while then just stall. Would occasionally restart. I could make it stall by manipulating the ICM connector while it was running. I have the terminals and the tools to repin the connector if it turns into this.
