Sounds more like an engine idle issue than a oil pressure issue. If the engine idle drops too low, the oil pump cannot provide sufficient oil pressure. If there is no oil light when the engine is idling normally, then there is no problem there.
Does the engine make any noise (knocking, rattling, etc.?) Before you condemn the oil pump, connect a mechanical oil pressure gauge to see what your oil pressure really is. If the mechanical gauge indicates good pressure, then you have an electrical issue somewhere.
