Check the fuel pressure at the rail when you step on the gas. Does it drop then it dies?

Can the pedal be pushed even a slight bit before it stalls?

Check the TPS and check its voltages with throttle closed, then lightly push on it and measure the voltages, are they all pretty much steady no big spikes at certian position?
