It could be the Crankshaft Position Sensor - My 1993 Bonneville with a 3.8 had the same issue, I replaced that and it works great now.
It had codes:
17, and 18 I think, or maybe 19 stored. Which was Cam Position sensor, and Crank position sensor problem.
The crankshaft position sensor is easy to replace, if you have access to a pulley puller, some tools and a jack or lift. Some motors need a special tool for an adjustable thing, but most dont have that anymore as I think they recalled it and replaced it on all.
I think they run about 30-60 for a new one, and takes about an hour to replace.
If it is intermittent start problem that may be it. Mine would start fine for a while, then sometimes after Id turn it off, it would just crank and crank, It would start after waiting about 5-30 mintues, while trying to crank it every couple minutes. When driving down the road, it sometimes would stall when turning or stopping.

Volvo 740 1991 stall

I own a 1992 740 and have been through the stalling issue. Tried everything mentioned in other suggestions. Expensive and aggravating. Finally turned out to be the spark module. My Volvo has the Rex/Regina engine management system and the module sits on the left front fender. The wire to the distributor is very long and runs to the bottom of the distributor. As a start I would check and clean all wires leading to and from the coil module. Sometimes the high voltage lead gets dirty or corroded. Remove each connector plug (one at a time) spray a little contact cleaner, re-insert it a couple of times. Sometimes just turning the high voltage lead will clean it a little.
Also check to be sure the manifold pressure module is properly connected. It has a thin vacuum hose running from the module (on the driver's side inner fender near the firewall) to the top of the intake manifold. If that hose is loose or disconnected, car will run rough and stall.

95 Ford Taurus SHO 3.2 stalls randomly

On one of the occasions when it won't start back up, someone will need to figure out if you have lost spark to the plugs or fuel to the injectors to be able to troubleshoot the problem.

Omni stall

I wouldn't think sensor problem. Need to monitor data to see what is not showing up. Some input to the PCM is not being seen. You need to monitor sensor data to see what disappears, it will lead you to the problem.
