If pumping the bulb keeps the engine running and the problem is happening only on the Port Engine with either of the two fuel lines and the Starboard engine will now operate properly on either fuel line then it certainly sounds like a problem specific to the Port Engine Itself.

If the Fuel Pumps were replaced 6 months ago and both engines ran fine for awhile, it sounds like you may have an early failure on the port engine fuel pump.

My next step would be to double check every connection and fuel suction line on the Port engine for a cracked hose or leaking filter cup gasket which could cause air to be pulled in to the LP fuel pump.

If this does not cure the problem I would then swap the LP fuel pumps between the two engines and see if the problem follows the fuel pump.
