After some advice i have a kubota 1550 which has had a problem with the rear lift arms not lifting heavy attatchments when the tractor is used for 20mins or more if you switch off and let the tractor cool it will then lift ok until hot again. This problem has now got worse where the lift arms will not stay up when the tractor is hot even on light lifting?? Any ideas

Most likely you need rebuild the lift, with rings and seals on the lift piston.
Second cause would be valve issue, but way less likely.
