    Check return line fitting at pump there is a check ball that can get stuck because of gov. ring in pump is coming apart. Pump will have to be removed and rebuilt by a pump shop.

    Check the "return connector" ON TOP of the inj. pump.. Remove all the fittings off the top of the pump & start the engine.. & reinstall 1x1 & see which one shuts it down.. I'll bet its the first one..

    Make sure there's nothing in the tank blocking the pick-up.
