Xs650 randomly dies

just finished my bobber build and I am having a problem. Bike will start and run awesome then suddenly dies (loses all voltage). Bike will not restart without jumping with car battery (running pamco/Pma with capacitor). I have tested pamco via pete's troubleshooting guide and test good. I have tested coil (dual output) getting 4.5ohm across posts and 15k from plug to plug. When bike is running voltage hovers between 13.4-14 depending on rpm. Dying is sudden and after cannot restart without external battery.

Any help is greatly appreciated.

I had a problem like that when I did my build it was the power wire from the stator(Pma) was hooked up wrong just something to look into. Good luck!
