Check and make sure the tank venting , check fuel cap .
If it dies again remove fuel cap and see if this helps.

DG has a good one.also if you can I have hooked up a bicycle pump with duct tape to the threads of the fuel fill spout and start it and give it a SLOW steady push on the pump with the motor at about 1/2 throttle
Good 1 DG don't know how I missed that 1
