If it is the trigger contacts then you HAVE to crack open the gearbox and clean them ... Sorry ...
But make sure it's not just a baad lipo first! ... Attach a lipo low voltage alarm to the lipo while it's in the gun and try shooting the gun... If the battery is fully charged and the lipo alarm goes off when trying to shoot on a fully charged and balanced lipo then its probably just a collapsed lipo cell ... (And the lipo needs to be replaced) ...
But it could (based on your description) sound like its the trigger contacts ...
Note my recomendation: You should not use lipo batterys on guns onless they have a mosfet installed ... (or you are prepared to clean or replace trigger contacts some times).. Because the increased amp they deliver can / will increase burns on the trigger contacts ... A mosfet eleminates trigger burns ...
