losing pressure? Help wanted

[circa3182]

I bought my mag offline and it was suppose to work fine. I used it once and everything went well although i only fired off of my deck about 300 balls. I put it away for a couple of months to use my micrococker. I recently sold my microcokcer and got out my old trusty mag.... I gassed her up and everything went great for the first 20 balls. But all of a sudden the trigger rod "lost pressure" and wouldn't allow me to fire anymore. I ungassed it and gassed it back same thing after about 15 balls. Can any one tell me what my problem is? I tahnk you in advance

if you're running on CO2 you might be freezing the valve by allowing liquid CO2 into it.

CO@

I am running CO2 and that is what i thought at first. So i put on my expansion chamber and ran remote and still had the same problem. Is it possible that once i freezed it up i have to wait a certain period of time before it unfreezes. All of your help is greatly appreciated.

I may be stupid

But I know I am not out of air. I have tried numerous times on full tanks and it still loses pressure. Anyone else know what is going on? Eek... I am so confused
