W2W 408 Dynoed today.....
What cam are you running? What valve springs? What spring pressure? Is the car still pulling or falling off?
It doesn't sound like a belt issue....
Its got to be in the coil packs if anything if the car is cutting out, are the fuel pumps keeping up with the runs, if the relay is shorted out that can cut fuel I know this happened to my car before when the relay went bad it would cut out completely and then jump back alive....

What happened to the SB I built? Just decide to upgrade?

1- 918 valve springs are at there limit and can easilly float at your level.
2-timing,I don't know your compression but I know too much or too little timing can cause it to break up.
3-12-1 A/F is alittle lean on a dyno.I would drop it back to 11-1 till you get the breakup problem fixed.
