Make sure the 4 bolts on the little fuel lift pump are tight. Had similar problems and it was getting air in the system. Did the exact same thing as you described when first getting started. Would run for 2 minutes or so then shut off like you hit the key. Found the leak by just turning key on and seeing bubbles of fuel come out at the lift pump. Tighten the 4 bolts and been good ever since.
