Stalling and not starting intermittently

I have a 95 Jeep Grand Cherokee that has less than 100k miles on it. So it’s in great shape for its age. The problem is that it has started to stall when driving it - it stalls when it is decelerating. It only does it every once in awhile. Also, it usually starts right back up but sometimes it will not. If I keep trying it will eventually restart.

My regular mechanic can’t figure out the exact problem so I was wondering if anyone out there has a clue. Thanks!
