My FE Galaxie's Electric fuel pump is wired direct to the Ignition curcuit.
I runs for a while great then chokes out and dies I'm thinking it needs a relay
or maybey a switch . Any Ideas?

Well, two things first off. I think any device that pulls more than 5-10 amps or is a long way from the battery or alternator should be controlled with a relay.

An electric fuel pump should be controlled with a relay and a safety switch of some sort, oil pressure, roll over, collision, etc.

With that said, I would doubt seriously that the fuel pump is causing your flooding problem. If it has a built in regulator, it might be going south, but sounds more like a carburetor problem to me.

That car came with a mechanical fuel pump driven off the cam. It supplied the correct volume and pressure of gasoline to the carburetor. My best guess is that the electric pump supplies so much pressure that the fuel is being forced past the needle and seat in the carb and is blowing raw fuel into the intake manifold. The motor is able to tolerate this for a little while each time you start it, but it soon succumbs to the ultra-rich mixture in the intake manifold. The cure is to install a stock mechanical fuel pump.

Absolutely utilize a relay and wire it correctly. If it's pushing too much fuel, get a regulator. However, you may have to run a "return" style fuel system. Or as mentioned before, go back to the mechanical pump.
