I think RX555 may be onto the answer. If your fuel pickup is toward the right side of the cell/tank, the long run through Turn 7 may be uncovering the pickup and emptying the float bowl enough that the engine dies just after you get onto the straight (which would occur somewhere near start/finish). Then, once you're going straight for a bit, the fuel pump catches up and the engine runs normal again.

By the way, you mention running up to 8500 rpm. Where are you doing that, and what gear and final drive? I don't quite hit 8000 in 5th, even with a 5.12 rear, and I was going faster on the front straight than you last weekend.

On the coils question, I've used both MSD Blaster2 and stock coils, and I've never had a problem with either.
