I would find a mechanical guage that will screw directly into the block to make 
sure my sensor hasn't gone bad.

-1600 DP Stock Engine ...16,000 miles on building it.

-VDO Oil Pressure gauge and sensor.....

When I start the engine , oil pressure is fine but after running for 
15 or so
minutes when oil temps get up to 200-205 ( oil pressure ok at 40-45 
psi )
but when I come up to a light or stop sign the oil pressure drops to 
0. Oil
light comes on and stays on until the rpm's raise above idle (900 
rpm) when I
drive off. ????

Then I go on my way and everything seems fine until I stop and the 
oil lights
comes on again.

When I first get in the bus the engine is warming up (120 to 180 
degess) the
first 15 minutes or so when I come to a stop sign at idle the oil 
pressure is
10-20 psi.... seems fine. Frustrating,,,,,,

I replaced the oil pressure relieve and pressure springs and the 
plugs which
increased my oil pressure but after 15 minutes (Oil temps 200-210) the
pressure drops to 0.

Any ideas?

Running Castrol HD 40 wt. It's hot here in Houston but never had the oil
pressure ever drop to 0 before like this. Engine was built 2 years 
ago. No
visible oil leaks anywhere.
