Trying to guess your way through a repair never works , Having a qualified Technicain with the proper diagnostic test equipment an knowledge does . It could be any number of thing's causing this problem . Looking at scan data ,checking IAC control by the PCM ,MAF sensor data . fuel trims ,EGR etc...

009 Idle Speed Problems Scan Data for EGR
007 Idle Speed Problems Scan Data for Idle

engine idle then take a screwdriver and hit lightly the MAF sensor if engine stall then maf is defect.

Most likely the fuel pump is worn out electricially or
binding & stopping mechanically

sounds like an alternator going. Should be 14 volts at battery with engine running at 1500 rpms

next time it won't run after it heats up, spray or pour water in crank sensor and see if it will start. I have seen new crank sensors go bad.

Replace crank sensor

if its a 3.8 liter pull off the vacuum hose on your fuel pressure regulator. if you get a hand full of gas after it stalls , thats your problem!! $45.00 at part store , just a snapring pliers to change it!! richie

Check ecm for part number 1228253. If it has this number in it replace it with a 16198264. Gm had trouble with that ecm for a cutting off problem. Mine would stall driving down the road and when I would put it neutral it would start back up and not have any trouble for the rest of the day. You must set the tps with a volt meter or scan tool.

I had the same problem with my 1994 Buick LeSabre. It turned out to be the idler solenoid that is mounted on the top of the engine where the fuel injector is located. The solenoid cost around $80.00 to replace it. I hope this helps you.
