i think i had the same problem as you (i'd play a point then the next it would sputter and leak from the bolt and quick latch). i found out that it was my luxe being over pressured, thus causing o-ring damage etc. ("Most likely is the reg creeping, either due to the 15/90 on the top of the regulator or the seat on the piston." this is straight from the stickies out of the trouble shooting [my advice read them over and over
they'll save you!]) I'd would then change the o-rings thinking it was just those but after 2 cycles of that, i knew it was something else. So then studied the way a luxe's air system worked
my theory is that its better to have a higher dwell, letting you have lower pressure in your reg so over pressurizing wont happen. i turned my dwell back to 13 from 10, i set my reg so that no air was let in the gun the i opened it 2 full 360* turns then i shot it over a chrono and fine tuned it from there.
my advice is to try to make a majority of your orings urethane, hater lube of any kind whether it be sauce or marm seems to be to think and will cause the bolt to stick, keep to using dow33 or monkey poo lube. lube the back oring of the bolt guide and the back part of your bolt. then do what i did.
(if you have to open the reg more than 5 full turns from closed so your bolt can fully cycle i suggest degassing your gun and upping the dwell one more milli second and repeat until the bolt fully cycles under 3 full turns from closed. once this is achieved you can fine tune it)
if this doesnt work im sorry for letting your read the entire thing
