I have a 1987 chevy pickup with a zz4 crate engine in it. It is set up with a Holley 4 barrel instead of fuel injection. It used to run great, then started shutting down on me while driving it. It was my brother's truck and he died, so I am not familiar with how it is set up. It runs for about 10 minutes when started cold, then dies. It will run for about 1 minute if I start it again immediately then dies again. It just shuts down like ignition switched off. Any ideas???
