case 580 C backhoe

Newbie I have a case 580 c backhoe loader-It seems to have a problem after it warms up-The boom will not work very well-also the arm and
bucket seem to not work as well-could this be the hydraulic pump?

Yes it could be the pump, but it could be a relief valve or something else. How is the oil condition, when were filters last cleaned or changed? You need to get a service manual, get the gauges it requires and do the diagnostic checks before you start throwing parts at it. An operator's manual will be helpful as well as those often give more oil, filter, and service interval info than a service manual. JMHO
