I had a similar problem with my GT350 that started from a random annoyance to a real pain in the tail. Be driving along, and the car would die. Restart, no problem. I thought my fuel pump was dying or the 725cfm Holley was in need of a rebuild or the Motorsprt Ignition module was dying. Turned out to be the fuel filter. The element was collapsing under load!
I has installed it in-line to my electric pump by the tank to pre-filter the gas before it got to the pump. Worked fine for quite some time before the problem surfaced. Luckily, I had decided to start with the easiest and cheapest parts before going deeper, which saved me a lot of pain and suffering! Once I replaced the filter, I have had no more problems, and I keep a spare in the tool kit just in case. I would suggest you replace the filter first, and go from there.
