1995 Jeep Cherokee car dies after going one block

Engine Mechanical problem
1995 Jeep Cherokee 6 cyl Four Wheel Drive Automatic

My car starts up and runs but after a couple minutes it just dies. I let it sit a minute or so it then starts right up and then a few blocks away it does it again. The first time it did it there was an odd smell, kind of like rotten eggs. But the smell was only that one time. The problem has been going on for about 2 weeks.
