Just because it was rebuilt, doesn't mean it was done correctly. I'm not trying to be an a-hole. Just telling the truth. This wouldn't be the first time. Do you know who built it? Where did they set up the bearing clearances? What did they use for an oil pump? Do you have an oil temp gauge? If so, what does the temp go to when you run it hard?
Personally, I think the clearances may be to big for the pressure to go to nothing when the oil gets hot. Even if it is reaching 275+ deg, it still should carry some oil pressure. A combo of excessive clearances and a stock, low volume pump that hasn't been shimmed, could certainly cause the problems you are having.

You remove the bypass from the cover of the pump. It is held in with a roll pin. Behind that roll pin is a spring that sits into the bypass valve. By adding shims(washers) between the pin and the bypass spring, it essentially stiffens the spring. This makes it harder to open the bypass, which will raise the pressure.
