dm5 losing pressure/velocity

so, dm5 fires good, chrono's good but when when i start playing the velocity drops to almost nothing. but if i start shooting fast it builds back up and shoots fine until i stop shooting again.

so basically i shoot wait 10 seconds then go to shoot again first balls rolls out of the barrel but if i keep shooting fast pressure builds back up and shoots fine as long as i dont stop shooting for more than roughly 10 seconds..

tore gun down all o rings are good, took noid out and tore apart everything good there. teflon taped all screws when reassembled

no leak anywhere just shoots like poo.....

cp reg, lpr is 5 turns out, chrono is good and consistent, this just happens after i start rapid firing.

and suggestions?

I'm assuming the battery was replaced and the dwell is 18-25?

First shot drop off. I'm sure there are tons of threads about it, but if you have already replaced the battery and checked your settings I would rebuild the bolt and regs.

If it happens during rapid fire that would point to ur lpr being an issue

I would blame the lube, but also make sure anti-bolt stick is turned on.
