During the idle, what's it doing?

1/ If it is gradually slowing down and dies, the LSN may be too rich.

2/ If it gradually speeds up and dies, the LSN may be too lean.

Since it dies when letting off the throttle as well, I'd guess #2.....the LSN may be too lean.

These arn't the only reasons, but it's a start. Your HSN may be too lean and that's all there is to it, but I'd start with observing the idle as above.

you might need to raise the idle via the idle screw .

ya id check the idle first, try giving the idle screw either half a turn, or maybe a whole turn
