If it's not that, make sure you're lpr isn't turned too far in. What is your dwell set at? Has that been touched? Lastly, do you have the stock rammer in the marker? If it has a TI rammer - that could also be your issue.
This. I would reset settings to stock, try a new brand name battery such as Energy paintball, Energizer, Duracell, etc., change the rammer orings, and make sure your LPR isn't adjusted too far in.
