I would use the script field on the scheduled import - specifically the post script. In this field you could check to see if the import set failed to create or if it was empty and retrigger the same scheduled import. To have it wait 10 min, you might need to trigger an event that triggers a script action and do the retrigger in the script action - that would allow you to pause the 10 minutes because you can set the event to happen in the future. Then your post script on the scheduled import should have a check to see if it has already tried 3 times and if so, then create the incident.
