Ya, you can rule out electral problem in your ignition system and focus on fuel. You are correct that the electric fuel pumps are located on the front of the engine. You should be able to hear the electric pump turning on for your motor when you turn the key into the on position.
Your description sounds like a vapor lock situation. I believe the procedures for vapor lock is to inspect your fuel system and cooling system. Check your fuel lines and check for leakage, and water that could be getting into your fuel lines. When was the last time you changed your impeller and thermostat? Check for leaks from all your hoses coming from your raw water pickup all the way to your exhaust manifolds. Make sure none of those tubes are leaking. If your impeller has not been changed in a long time I would check that because if your not getting adequate water circulating you can overheat which is a cause of vapor lock. Did you happen to look at your temp gauge on your dash? When was the last time you changed your fuel water separator? Or at least drained the water out of the existing one? That was a cause of my vapor lock issue this summer. Also bad gas is possible depending on where you filled up or how long its been since you ran the engine.
Other than that I'm all out of ideas of what could be causing your vapor lock situation.
