Carb.? Float sticking? Rebuild or replace
It could be a number of things...such as...idle set to low, poor carb set up, low fuel pressure from pump and yes..a plugged fuel filter...start with the filter first and then move to the larger more expensive components.
Replace the fuel filter.
replace the fuel filter
I would replace the fuel filter. It might be letting just enough fuel by to start the engine, but not let it run very long. When the engine starves itself out (stalls) a little more fuel trickles through the plugged filter so you can restart the engine.
clean jets and check fuel filter
Could be as simple as a plugged fuel filter. Or faulty coil.
Have fuel filter or fuel injector checked..
