93 Z28 Shutting Down

My pops just picked up a clean 93 Z28 with 102,000 miles on it.Car has been great for the first few weeks,but now its developed a strange issue. i was driving it yesterday going about 35 mph in 3rd gear running roughly 2500 rpm and the car just shut off. When i say shut off i mean it didnt spit and sputter it just stopped accelarating. I pushed the clutch in and restarted the car and it started right up and all was well. About 6 miles later it did the same thing again,stopped accelarating pushed the clutch in and noticed it was dead,car restarted instantly and kept driving. It has done this twice now and im getting a little concerened. I dont believe its fuel related because if it was some sort of fuel issue i would believe it would sputter out vs. just cutting off like a switch had been thrown. Any sugestions where to start?? Thanks for any suggestions.

I'd throw a fuel pressure gauge on it and see what happens to the pressure when it cuts out. A bad pump can do that.



Yep its slow.

have also seen ignition switches causing this problem not the key cylinder the switch located on the column try jiggling the key and see if car shuts off or stumbles
