Oil pressure & engine stalling

My 93 Roadmaster oil pressure seems to run high, near the top of the gauge. This doesn't concern me as much as the other problem. While driving, the engine will stall for a second or two, then turn back on. Afterwards, the climate control will count backwards from 30 two times and all seems normal. Otherwise, the car seems to run fine. Just wondering where I should start looking to fix this...

The oil pressure, get a mechanical gage on the engine where the op gage is attached and get an actual reading, look for bad grounds through out the engine grounding circuits.
