Front end loader{is this normal?)

[legs]

When I curl the bucket all the way up to the end of travel the engine will stall,but when I curl the bucket all the way down the engine does not stall ,until maybe 3 or 4 seconds.when the bucket is in between up and down travel I can raise the bucket by hand several inches.If I cycle the bucket in and out a few times it will not do this.I have blew the cylinder and it will work ok for a while.I do not see any leaks anywhere.This is not normal is it?Thanks

First part is about curl and stall is normal.
Seconds part not so much.
You could be sucking air into the system, but if you were doing that it should affect lift too.
It might be possible you have internal seals in the curl cylinders that need replaced.
Or you could have loose pistons?
