Dozer works fine when cold but when it warms up, gets hot, it looses power.
I let it cool down and it will move again.
Any help please.

Is that in both directions ? Sounds like clutch pack problems of slipping - internal leakage or worn clutch pack with low hyd pressure .

Total lack of power.  Dozer doesn't have enough power to turn the tracks but if you leave it sit for a while and cool down it works again.

Is that in all 3 gears ? Seen one where they were running in 3rd and complained no power after a bit - overheating from slipping .

It does it in all gears.  Works perfect until it warms up and then looses all power

Need to check pressure and for leakage , from front pump , torque converter and leaking or worn clutch pack - low hyd pressure to clutches
