Splitter hydraulics

I put a new engine in this thing probably two years ago, seems like it will split about anything when I first
start it but after about 20 minutes maybe the hydraulic oil gets warmed up and it doesn?t wanna split
anything, any ideas what the issue could be or what I could do to get more power?

Is there a suction hose to a reservoir,or is it all self contained in that blue box? A friend was having trouble with the suction hose collapsing on his.
 
Week after warm up is usually indication of worn pump. Looks like that pump is in the tank so not how you could replace it. You can get a gauge and put on the output and check it or one more thing change to a little heavier weight oil.
 
I will second thinking the pump is getting worn. Tee a gauge into the line that extends the cylinder. Check and see what your pressure you have when it is hot and then cold. Also feel the valve to see if it is getting hot. A bad relief valve that is leaking can overheat the oil and make it lose pressure. Warm enough you can not hold it very long would be kind of normal. So hot you can not hold it at all is too hot. An inferred heat gun would be best. Anything under 130-150 degrees is OK. Over than and your pushing it.
