Check the electrical connections on the fuel pump as they live in a pretty horrid environment.

If it does it all the time then I'd say carb balance pipe or carb vent valve as they are both common faults. If they are intermittant though, then check the crank sensor wiring to make sure it isn't rubbing on the driveshaft and check the electrical connector is good.
