I've found that some systems reset the CMOS to default dates...if the PSU is turned off via its power switch.

Aside from that, what you report sounds like a weakening CMOS battery or a system CMOS problem.

Try leaving it out for awhile
You will need to reset date and time

Make sure you have the CMOS battery in the correct way.
It is easy to put the battery in up-side down.
Make sure the side with the + or label markings is facing UP.
Make sure the battery is pushed all the way down till you hear it click into place.
If the battery is new, make sure you have the correct one.
