The problem sounds like the solenoid that locks up the torque converter. This will not set a code or turn on the check engine light. The car will restart each time after it stalls. This will happen when you are comming to a stop or turning a corner. At times, you can start the car in neutral but when you put it in drive or reverse, it will again stall.
This can also happen after you have driven the car and parked it. When you restart the car, it may stall when you try to drive it because the solenoid is still locked from when you pulled into the parking spot.
Try to free it up by driving the car about 32 mph in drive (drive with the square around the D) where the overdrive and lock up torque converter will work. At 32 - 34 mph, pull the shifter down to the next Drive (D without the box around it) and you should feel the bump of the torque converter unlocking. Then put it back into the upper drive location and you will feel it lock up agian. Repeat this about 20 times and see if this does not help. These can start becomming mechanically "Sticky" and cycling them 10 - 30 times can help.
There is also a 6 wire connector on the forward (front of the car) side of the transmission. This connector might be dirty. Clean it with electrical contact cleaner (spray type) and reconnect it to the transmission. This connector is probably not the problem but worth lookign at anyway.
There is also a small port in the valve body of the transmission that if plugged, it can cause this problem. I feel it is most likely a "Sticky" soleniod that locks up the torque converter and makes the car stall just like comming to a stop in a standard transmission car without pushing in the clutch.

Sounds like the solenoid that locks up the torque converter. This is a mechanical device that locks up the torque converter at around 31 MPH. Pull the shifter into a lower gear (normal drive rather than overdrive) while you re driving about 33 mph. You will feel the car **** a little as it drops the lock up soleniod pin out. Shift it back and forth between overdrive and drive at this speed...33 mph or so.... as long as you can feel this happening a few times. I'd say to do it 10 - 30 times. This will not hurt anything but if it is mechanically sticking, it might help to solve the problem
There are a few other things I might suggest but this will first be a good test. If you drive the car in second gear (much slower to not over rev the engine), it should not ever stall because the torque converter should not lock up anyway.
This problem will not set an OBDII code or turn the check engine light on at all. This will make your car stall when comming to a stop or turning a corner. The car will quickly restart. This can be a very intermitent problem.

See Figure 1
The ECM uses the camshaft signal to determine the position of the No. 1 cylinder piston during its power stroke. The signal is used by the ECM to calculate fuel injection mode of operation.
If the cam signal is lost while the engine is running, the fuel injection system will shift to a calculated fuel injected mode based on the last fuel injection pulse, and the engine will continue to run.
