Default So close, yet so far... Thoughts?

Ok, so i just installed a rebuilt KA24DE in the coupe. I get it to run for about 10-15 seconds then it stumbles and dies. It bogs completely with throttle input. It kinda acts like its running out of gas.

When it idling, it's smooth, sounds nice, then a spit and a sputter then stalls. Turn the key off, back on, start engine, repeat above description.

Ideas?

I have the supply line connected thru the lower line (that runs toward the front of fuel rail) andthe return line connected to the upper line (that runs off of the FPR). the MAF is connected w/ uncut plug (i know that doesnt mean much) and I've been all over the connections and vacuum lines. evrything seems ok
