well i dont know i guess there is something wrong, again i should probably not be doing this on the block and actually driving it but, i've done this with the shockwave before reved it on a block and engine didn't quit like this. maybe the 2nd gear is not set correctly? if it's happening when it's accelerating maybe it's trying to switch gears? i made a video of what's happening, here's the link:
