The fact that you jumped him two times in a short period is good, he's hurt bad. I believe you will find him today not far from the last spot. Good luck, post the pics
Good rule of thumb is, if you know you made a bad hit...leave em lay. Liver/gut hits, the longer the better. Min 4hrs is my rule, longer if possible. They will usually lay down within a short distance. If left be, they will often die where they laid down initially.
