These engines hold about 7.5 quarts, so if you were down three you were down quite a bit.

Wonder if its a main bearing or a cam bearing? When you get on it the oil pressure could force it to shut up because it spikes pretty high.

Start cracking the injector lines and see if you can narrow it down. At this point you are guessing. Also I'd pull the valve cover and remove the cam, see how the cam bearings look.
