Welcome to the forum. You've come to the right place for all things A4 related.
You are running on one carburetor bowl of fuel. When that runs out the engine quits. It sounds like the OPSS is not working correctly - even though it is new. Bypass or short across the OPSS temporarily and see if the shut downs go away.If this does not cure the shut downs we'll go to the next step.
BTW what oil pressure are you running? Maybe you don't have enough oil pressure to close the OPSS.
