I would guess MAP sensor, or coolant temp sensor, not letting the system know how much fuel/air the motor needs to run correctly when cold.
This...errr these....


I would check the coolant temp sensor or possibly even a bad thermostat. If the coolant sensor is going bad the car is going to run very rich and you should see your gas mileage really start to tank.

The whole "not heating up properly" thing and the stalling thing might be two separate issues though.
