OK. You'll need a fuel pressure gauge here. You can borrow one for free from Autozone, Advance, etc. It attaches on the fuel rail on top of the engine, very easy. Fuel pressure must be 55-62psi. What you're describing is a classic low fuel pressure situation, it's definitely where I'd start looking.
