Re: Gauges work fine when engine's started, then oil...
Start by checking the ground strap to the engine, and engine to body. The oil pressure sender unit may be bad. You may have to hook up an oil pressure gauge to the oil pressure sender port to verify proper oil pressure. Senders are cheap- I would just replace it and go from there.
