 I had a similar thing happen.  I had removed the oil pump and cleaned it up and reassembled it.  Started the engine and it only ran a minute or two before it seized up and stopped...damaged a couple of valves, too.
What happened? The steel shaft, due to lack of lubrication, seized in the aluminum housing it was running in.  No bearings.  What caused it?  When I reassembled it I made sure all was clean...I ASSUMED the oil being pumped up would lubricate it..not so.
So, I disassembled it, forced out the steel shaft and cleaned up the aluminum area it ran in.  This time, I coated all the parts with heavy oil and reassembled it.  No more problem and it was lubricated well until the oil was up in the unit and then furnished lubrication.
So, in summation, when I re assembled it the first time and put it back together, it was dry...dumb me.
