Good Morning Philip, a couple things could be an issue here. You could be sucking air into the fuel system, or you could have a damaged fuel nozzle.

To check for aerated fuel you would need to either check inside the tank for bubbles while its running or install a clear fuel line on the return to the tank and see if bubbles are there.

If you had fuel in the oil, I would lean towards there may be an issue with over fueling and the nozzle are having issues with over fueling.
