I'm thinking fuel pump:

test drove scoot (yep shut off going up to 50mph,) got scoot back home after pushing her about a 1/4 mile, chech fuel line from tank to pump (gas is flowing good), took off pump and looked in side, as far as I could tell pump look ok), put back on and cranked, (no go) sprayed carb cleaner in intake line and scoot well start and runn for a few seconds, gas in fuel filter about a foot from carb. I think fuel pump.
