2000 Dodge Durango V8 magnum. Oil pressure will drop to 0 sometimes at stop lights. Pressure jumps back up when gas pedal is pressed to go
Check your oil level. I have a 98 Dakota with the 5.2L Magnum V8 and this has happened to me a few times - these engines tend to burn oil and its likely you're a quart low.
152K you could be getting bearing clearance increases that will cause this, or it could just be a sender malfunction, I would put a manual oil pressure gauge on it for a while, that way you can see if the oil pressure is actually dropping out indicating a more severe problem or if it is just the sender.
Dodge had a big problem with oil pumps going out on these. My Dakota would momentarily lose oil pressure after getting off the highway. (Gauge went to zero, light came on) Dealer put 5 sending units in it before they finally would admit to problem. By the time they fixed it, they also had to replace 2 main bearings.
