Not enough info.
How was the tune both timing and A/F ratio. What rpm did you drop to when you hit 4th? Gonna take a good deal of info for anyone to know what possibly happened. You have pics?

5 degrees out, hit it at 3200 on a WOT switch, the whole back of the ls6 intake is gone and major cracking all around the intake, no damage to the block, will post pics tomorrow

Yes it is possible to lose the fuel pump and go lean, but you'd have more then a intake problem. Piston(s) would be fucked with no fuel and all that heat inside the cylinder
