I have a 00 Durango 4.7 4WD. problem started with fuel gauge dropping to "E" then the ABS and Brake lights came on. now oil pressure gauge drops to 0 and the check gauges light comes on. Then they all go back to normal. They do this intermittently. Anyone have any ideas?

 

start by checking for a loose ground or plug in the wire loom (it almost seems like these systems share some sort of the wire harness)

another thing that im going to ask is are you actually loosing oil pressure (hearing valve chatter, ect) i would suggest hooking up a mechanical gauge if you can just to see if the pressure really drops when your dash gauge does.
