If you hear a rattle at the front end of the engine, then it needs a timing chain. Very common on GMs of this era, you are lucky to get more than 50k out of a stock chain. It's about a three hour job if you have a lift, a little hard on the back if you don't since pretty much all the work is done through the wheelwell.

My car did the exact same thing,, stall and start right back up and it was the crank p sensor,,,
But, the cam one is no problem to change, just two screws and you're done.
If it still does it, then you will know!!

but that said...
the sensor can and does go bad. the 3800, being the first SFI engine in the US, has relied on that little piece of voodoo for decades in various incantations. they are expensive, which is why there are none in the boneyards, and contrary to rumor, the 3.3 engine sensor will not drive the 3.8.
swap it out and put another 200K on it. Its not wards all time best engine worldwide frivolously.
