Fuel Pump?

Could be coil.

So, I'd look at electrical and ignition still. Check your kill switch, ignition switch, look at anything that could be intermittent and take it from there. I'm not saying it can't be fuel, but still sounds electrical to me.

I agree. With the quick cut out, get the VOM out. I suggest a good look at the ignition key switch. Get the VOM hooked up and wiggle/turn the key. I also suggest measuring voltage out of it as well as resistance across it's contacts. (B and I terminal) It should be a near zero reading. Then, get volts at the ballast resistor going in and out.

Starts good at first then looses power/runs out of gas? Tank vent.It's real easy to check. When it happens open the gas cap and start it if that works a dirt dobber (wasp) built a home in the vent.

Long time ago I had an old dodge panel truck as I threw money at it I put on a locking gas cap that wasn't vented. Ran fine for 10mi or so then ran out of gas. NO power but idled fine. I thew the kitchen sink at it. Then it happened again a friend took the gas cap off and the tank popped back into shape. That old slant 6 really pulled a vacuum!   

Went to take the pickup tube out today and only the 90 degree fitting at the tank came out. Isn't the pickup tube supposed to be attached? There was some more junk in the anit siphon, but not enough to block any flow. Engine fired right up in the driveway with a full tank of fuel.
