1995 z28 runs and then dies
I have had this problem for about 4 months. It will run from anywhere between 15 and 30 mins, but then it dies. Then after it dies it won't start again for about 2 hours or so, and then it does the same thing all over again. It also failed a light noid test. I've asked all around about the problem, but no one can be for sure what is the problem. It has a brand new ecm and the distributor was replaced last November. So if anyone could help I would really appreciate any ideas.
Have you scanned it for codes? Have you checked the fuel pressure? Was the distributor replaced before or after the problem (not clear whether "last November" = 2008 or 2009)? By "failed a light noid test" do you mean that you did not get injector pulsing when it wouldn't start? There are some codes that will shut down the injectors.
Is the engine stock or modified?

I did scan it but the scanner says no link. Checked for fuel pressure and its fine. The distributor was replaced in 2008. As for the light noid test, it fails when I'm trying to crank it after the car dies. The engine is stock. Also I don't get a check engine light which probably explains why the scanner doesn't link up. I've also checked every fuse. thanks for the help
When did you check the fuel pressure, right after it stopped running, or after it had cooled off?
Mine was doing the same thing at one point. I would wait until the engine cooled and checked the pressure, it was fine at about 43 psi. Then I checked it right after it died, still hot. Around 5 psi. The pump was overheating and failing, but when it cooled off it was fine. Just my experience.
