88 GMC 2500 350 motor

This problem just started, When idling the motor wants to or will just shut off like it was out of fuel. It starts back up with no problem. When on the highway, runs like a champ. Any suggestions?

I've seen a few of these motors have egr valves that open wide open at idle causing a huge vacuum leak causing it to die
