The two should not be related. There are two things to consider, and I'm sorry to admit I'm not your expert on either one here. One is that many vehicles since the mid '90s have speed-sensitive power steering assist. As vehicle speed increases, power assist goes down to provide more road feel and better fuel mileage. More power assist is needed during low-speed maneuvers such as parallel parking. That puts added load on the engine. The Engine Computer is responsible for maintaining proper idle speed. If it's not responding to the increased load as the truck slows down, idle speed could drop too low leading to stalling.
There can also be an issue with any repairs that involve disconnecting the battery. On some vehicles the Engine Computer has to relearn when to be in control of idle speed and until it does, idle speed can be too low. On Chryslers, for example, the engine may not even start unless the gas pedal is held down a little and it won't give the nice "idle flare-up" to 1500 rpm when the engine is started until "minimum throttle" is relearned. That is done very easily by just driving at highway speed, then coasting for at least seven seconds. Until that is done, stalling at stop signs is a common complaint.
If you're having stalling problems while driving, that's a totally different symptom, and again, I'm not expert enough on your vehicle to address that. I can give you some pointers that pertain to older vehicles, but you might want to consider posting a new question so the other experts can see it.
