Maybe a bit more information? You say 350 TBI, but you don't mention what controller. Did you use the OEM ECU and wiring harness, and if so did you send it in to one of the reputable geeks that strips out unnecessary programming and wiring? It sure sounds like an OEM security glitch is taking you out.

sorry guys, I'm using a motor out of a 91 camaro and harness, ecu and injection unit from Fuel Injection Specialties. There should be no antitheft issues involved. Fuel lines and filter have been blown out and checked multiple times, fuel pressure is more than adequate to keep motor running.

Your words about fuel pressure are a concern. For that engine the fuel pressure is spec'd 9-13psig, and the warning I see is any lower or higher can cause problems. Do you have a regulator on the fuel, and have you verified pressure at the engine with a gauge? I'd be adjusting for 11psig, given the spec's.
