It may not be your engine. It may be your fuel system. A couple of things to try. #1 loosen your fuel filler cap or remove it, pump up the bulb and try the engine. Mud daubbers have been known to plug up the gas tank vents. The fuel pumps can't pull fuel until the vacuum that forms in the fuel tank is relieved. Plugged vents can exhibit symptoms similar to yours. If that does not work, connect the fuel line to a portable tank or gas can and run the engine off that. If the engine runs well, the problem is in the fuel delivery system and not your engine. Good luck!

What did it turn out to be? Sounds like loose wire someplace that kills the ECU?
