Weird cursor issue

    Lets say I have a temp layer made out of selected items from another layer and I am trying to look through 2 attributes in that layer with searchCursor:

    union_test = "C:/Workspace/Sandbox/MapChangeProject/intersects.gdb/footprint_cslf_union_10418"
    selects = arcpy.SelectLayerByAttribute_management(union_test, "NEW_SELECTION", "FID_master_merge_footprints_20181004 <> -1 and FID_cslf_20181004 <> -1 and DFIRM_ID like \''+ {} +'%\'".format(fip))
    selector = arcpy.MakeFeatureLayer_management(selects, 'selects_lyr')


    I've noticed in testing that if I run the following in my terminal once, it works fine, and prints as expected. But if I try to run it again, nothing prints. Why would this be happening? Is it due to the selector layer just being temporary or something else. For runtime sake, I was trying to avoid using arcpy.CopyFeatures_management to make a physical feature layer that I would need to store in a .gdb somewhere.

    cursor = arcpy.da.SearchCursor(selector,['Pre_Zone', 'NEW_ZONE'])
    for row in cursor:
    pzone_value = row[0]
    nzone_value = row[1]
    test = placer(pzone_value, nzone_value)
    print(test)
