There are only a few things that could cause this issue, so we'll get to the bottom of it quite quickly.
When you fire the marker, the times it fails, does the bolt move forward with normal force or does it seem weaker than usual? If that's the case, you're almost certainly looking at a problem focussed around your battery/solenoid, or qev's. your qev's may be damaged, preventing flow of air to the rammer, or even clogged up with filth because you don't clean it enough. Naughty naughty. Most likely: your battery is dead, including the one you replaced it with, and there isn't enough juice in it to open the solenoid long enough to drive your rammer with sufficient force to open the valve long enough to fire a shot at normal velocity. This would be consistent with the fact that you get a couple shots before it craps out, as the battery will slowly regain a bit of charge while inactive, then lose it all when you shoot a few off. If you go buy a fresh energiser/duracell from your local supermarket and THAT doesn't fix it, AND your QEVs are looking just fine, AND your LPR is not screwed in all the way, then I suggest sending it off to planet so they can check your noid out.
