Jeep stalls at stop signs, traffic lights but only when temp outside is hot on 1994 Jeep Grand Cherokee

This does not happen in cold weather; only when hot and humid outside.Usually starts right back up again but not always.Fuel pump, MAF sensor replaced already; no difference. Thanks for any suggestions.

Thanks for your help. My mechanic says we may as well wait til hot weather again to see if problem continues (it has for the last two summers). I appreciate your help.
