First, check engine oil level to make sure it's not low. If oil level is good, check or replace throttle positioning sensor

Does it only do it after it's warmed up and not when it's cold

Sounds like a bad IAC (Idle Air Control) valve. When the engine stalls the oil pressure will go to zero because the oil pump is not pumping with the engine stopped. That's normal. You'll also get a charging system warning light as well. HTH. -Jim
