It's getting annoying, I have to curl the bucket back up about every 15 seconds when I have a load on or else i will lose the load in the bucket. There are no external leaks, but I'm not sure how to fix this or find where the leak is. I have about 950 hours on it, factory remotes installed and a new cinematic kit about 100 hours ago (it worked great until recently) Any ideas out there?

What is a cinematic kit? Not knowing what it is I don't would have any impact on the porblem.
Here is a way to identifiy if leakage is in a cylinder packing or in the control valve.
Put some weight in the bucket. Then with loader down bucket on the ground, follow the hydraulic line from rod end of a bucket cylinder back to the control valve and disconnect that QD. Start tractor and raise the load then watch to see if it drifts down same as it has been. If it drifts the leakage is in one or both of the cyinders. If it does not drift, leakage in in the control valve. Could be something as simple as spool not coming to correct neutral.

Hi Dennis, the cinematic kit was a new replacment set of ball and sockets in the joystick mechanism. The origionals were made of plastic and wore out, the replacement are stainless i believe. Anyhow, I will try your sugestion thanks.

Most of the time, the cylinders need rebuilding as they leak by internally. They should be rebuilt in pairs. You can prove to yourself it's not the valve by swapping the dump/curl hoses with the lift/lower hoses.

I've taken those cylinders apart. They have no washer or SEAL of any kind under the bolt that holds the piston to the rod...leaks through the threads/piston hole.
I've seen the piston to rod bolts loose on most of the curl cylinders too. Haven't NEEDED to repair the lift cylinders...never had an issue with them bleeding down ??!!
I just use some aluminum flat rubber impregnated a/c compressor washers from GM a/c compressor manifolds. Slows the bleed down quite a bit...they're thin enough to have PLENTY of threads left protruding out of the locknut too... HTH
