I had this same problem last year on way to National Corvette museum. On I-75 north in Georgia. Cruising along at 75 mph fuel pressure drops, pull over called AAA for tow. After setting for awhile at auto shop I was able to restart car. At this point I decided to go back home ( The Villages ). Car stalled 3 more times by the time I got home.
After checking I was able to isolate the cause of the failure. Fuel pump
relay# 1 would lose power at times.
Using the 8A section page 8A-22-6. That relay controls fuel pump relay #2
Replace fuel pump relay #1( 20 plus years old ) and car started right up.
No guarantee that this might be your problem, but it gives you something
to look at.
Hope this may help you.
