1995 V6 Mustang Died Instantly Driving On Highway. Help!!

Hi Stangnet, longtime lurker, and I need your help. Today while driving to see family for Christmas, the car appeared to be running perfect, and I was traveling around 70mph then suddenly the engine died. I was not able to start it, and stranded me. I parked the car in an empty parking lot, and am going to deal with it Sunday. If you would have asked me 10 seconds before it failed, I would have said was running perfect, it happened instantaneous. The radio and still worked, so it is unlikely it had anything to do with the battery. It also appeared to still receive fuel pressure. I am lost to what it could be, and need help diagnosing the problem. What would cause that to happen?? Thanks!!
