The cam sensor is a hall effect sensor as well but the engine can run without it so I doubt this is it.
The fact that it is stalling once it warms up tells us that this could be a sensor used during closed loop or the purge valve. Basically when the engine is warming up, it runs off of a pre programmed set of parameters. This means it is not adjusting based on what it is seeing with the sensors. Plus it is not running the purge valve until it is warm.
I would start with removing the purge and seeing if there is any carbon build up or if it looks like the plunger is stuck. If it is then the PCM is turning it on and it is sticking open which puts to much fuel in the engine stalling it.
Normally it will run rough at first then stalls and you can smell fuel. If this is not happening then we may need to hook up a scan tool to see what the o2 sensor are telling us when it is getting ready to stall. This will tell us if it is fuel related which depending on what it is doing can pint us to different areas of concern.
