Car stalling at low RPM's

So, I am having this problem with my engine stalling at low rpm's. The rpm's goes to zero and the engine shuts off.

This only happens when travelling at low speeds (e.G. Slowly accelerating from a stop, braking, moving in stop and go traffic).

This never happens when I am travelling above ten mph (e.G. If I am coasting at forty mph and let my foot off the gas, the rpm's can go down to five hundred rpm's but it will never stall in this case).

After the stall, I can always put the car in park, turn the ignition and it will turn back on again.

I have not noticed any electrical problems that occur when this happens (the radio stays on during the stall and the lights do not dim).

My car was part of that Chevrolet ignition switch recall, but I took it to the dealership which (hopefully) repaired it.

Any input would be most appreciated!
