Well... we need a few more details first...

It could be too lean...(probably) or too rich...or you might have an air leak...etc. etc.

What are the symptoms...what does it sound like just before it quits?

If the high speed needle is too lean it can cause dead sticks

Or if the low speed needle is too rich fuel can build up in the crank case and cause a dead stick.

The Evolution 46 engine has a limiter on the high speed needle, you only can adjust it about 1/2 turn.

Before you do anything, you should check the glow plug, if the coil is distorted or looks odd in any way, change it - before you go tweaking needles.
