Huge drop off when firing Electra DX LED, Help!
 

I just got a spyder electra DX LED. I gassed it up and it didnt leak. I started shooting it and once i shoot 5 shots in a row the pressure will drop off so low that the gun stops shooting and uncocks. Its not the HPA tank because it works great on my other gun. I think its the HP regulator in the ASA adaptor. If there a way to fix this? or do i just have to get a new HP regulator?
