You can't go by the gage on the dash, you need to hook up a manifold gage to get an accurate reading. Did you check the oil filter bypass valve AKA oil relief valve?

NOT LACK OF OIL AT ALL! FACTORY OIL PUMP OF AFTERMARKET HIGH VOLUME OIL PUMP? HOPEFULLY YOU INSTALLED DEFI GAUDE SENSOR IN PLACE OF OLD OIL PRESSURE SENSOR! ALSO OIL WEIGHT CAN AFFECT THIS ISSUE! AND LASTLY PRESSURE RELIEF VALVE MAY BE MALFUNCTIONING IN THE PUMP ITSELF
You should check with Isuzu if high oil pressure will indeed cause a shutdown. In some applications, maybe many of them, the oil pressure sensor is what keeps the fuel pump running after the engine is running.
You will need it diagnosed when it happens for sure. At that time, need to check for spark (ignition failure), and gas (is the pump still turning on?). Shutting down while driving is computer related, usually it's the ignition system or a fuel problem. Check with Isuzu about the oil pressure sensor. Let us know. I would like to know.
I would check the oil pressure sensor and the oil pump itself. You can take the sensor out and use a mechanical gauge to check the oil pressure. If the oil pressure is within specs, you need a new sensor, if not, you need a new pump.
I am not certain, but, most vw's have 2 oil pressure sensors. One is on the head, one down near the oil filter. Maybe the other one is bad..Auto zone or NAPA could tell you if yours has two (2)..
My daughter's '87 jetta DID HAVE the oil pump fail (at ++200,000 miles), it was easy to change, about $150 and 2 hrs and a pair of ramps. Had the oil pump out and in my hand in about 40 minutes.
Sounds like you could just have electrical gremlins under the dash. Have someone (or you) actually put a pressure guage on the oil pressure connection to look for pressure, don't burn up your engine.
