Check the little brass check needle under the accelerator squirters to see if it is sticking closed after sitting. I would pull the carb. off and remove the two screws that hold the nozzles in place and turn the carb. over, if it will fall out without tapping on the carb. your good, if not it is sticking shut Let us know what you find out.

The symptoms are pointing in too many directions. The heat/E10 could be evaping the fuel out of the bowl. I'd fill the bowl/pump several shots & see if it will stay runnning. if it does then a thick base gasket may help & it may just have to be tolerated if it sits for that long (heat riser not shut closed I'm assuming). If it dont stay running I would plumb a can of gas to the pump inlet which would eliminate the rear hard line/2 short neoprene hoses/tank/sock. All that is left is the pump/pushrod (it should be ~3.250" iirc)

If you have any rubber fuel line between the fuel pump and the tank check it real close for any cracks where the pump could pull in air when trying to pull fuel from the tank. I have seen it before as once you get the fuel to the pump it works for a bit but because of cracks in the suction side it bleeds off the fuel in the suction side and wont start again later. You most likely pulled much more vacum with the mighty vac pump the the fuel pump makes so that may be why it worked like that. But I would check the suction lines for small crack. Not big enough to cause a fuel leak problem but enough to pull in air on the suction side. Course an electric fuel pump back by the tank is a good idea. Ron
