I'm thinking it might be fuel related. It's possible that you're not getting enough fuel to the cylinders for it to start up and stay running. By taking off the ignition wire and turning over the engine you're letting more fuel get into the cylinders. Then when you put it back on, there is enough fuel for it to ignite and stay running. I would check out the fuel pump.
