Narrative:

Pdx approach called me with a point out (po) so I brought up the data block (DB) and approved the po. Later on the DB dropped of my scope by itself. I called pdx and they told me that they had lost radar contact on the aircraft. I still had a radar target. It appears that by pdx losing radar on the aircraft it caused a subsequent removal of the DB from my scope. I was relying on that DB since I did not have a strip with the po information on it. I didn't notice if the aircraft was showing in the edst. In any event; it is imperative that the DB I brought up remain there until I drop it off or it is rs'd from the system. Recommendation; prevent premature DB drops when stars loses radar on target.
