There's fuel supply and fuel pressure regulation. The fuel pressure is
regulated by the small can like regulator on the top left of the engine.
It has a hose attached and its attached to the fuel rail. With the
engine OFF pull off its rubber (vacuum) hose; if fuel drips out the
regulator is defective.
An intermittent fuel pump or fuel pump relay, more likely the latter,
would cause the problem you describe - no fuel. Eventually it will quit
while you're driving, causing a stall.
