For the ec2 products there is now a capacitystatus attribute that can be either UnusedCapacityReservation, AllocatedCapacityReservation or Used.
This is causing collisions and any products are being excluded from the pricing results. Here is an example of the three products that would collide on the hash "t2.medium|Linux|Shared|No License required|NA|US West (Oregon)"

For the moment I am adding an additional filter to "def _generate_reverse_sku_mapping":
if product['attributes']['capacitystatus'] != 'Used':
continue
to get around the problem.
