Well two things to look at. Fuel and or ignition. When some ignition components get warm they break down and don't work or they get intermittent.
2nd. Is motor getting adequate fuel at all times? Post back

When it sputters and stalls have you tried squeezing the primer bulb to see if it revies it temporarily?
