LS2 engine has been together for 1000 miles and occassionally at WOT the oil pressure flat lines at zero. At hot idle the pressure is 30-35psi and under load the pressure comes up to 45-50psi.

This sounds like an electrical issue to me with the sensor rather than anything mechanical. Has anyone seen this?

My first thought was electric also. Plug in a mechanical gauge somewhere, and check it out. I hope it is electric so you don't have to pull the pan.
