Never had much success with cleaning them out. If the egr is sticking, it will run rough, you can keep it running with throttle though, it is basically a large vacuum leak. If it won't start, tap on the base of it with something metallic, and see if it changes. Or even try tapping on it if it is running rough. One other thing to consider, and may be the higher of the probabilities, is the idle speed control motor. It has a nose switch as part of the unit, and if that switch is still indicating the throttle at idle when it is not, it will retract all the way trying to control the speed, and the result will be a stall. This can also create a hard start for a short time until the shaft extends opening the throttle plate. Considering your conditions, and this happening around town, it is the strongest of the possibilities. You might be able to confirm this by disconnecting the isc when the vehicle is at a decent idle speed, and driving like you've been. If it no longer stalls, plug it in and see if it returns. Or, check it after a stall. If the ISC shaft is fully retracted to where there is a gap between it and the cam, that is your cause.
