cloning the wrong way?

Apparently, your insert seems to be toxic to the cells. I think Stratagene
has a kit for cloning such difficult genes. It could be using the SURE
cells, but I am not sure (no pun intended).

You don't need to sequence your clones to confirm your orientation (your
digest did that) but it is always a good idea to sequence a few clones when
cloning PCR products. This is especially important when you use Taq
polymerase, which has an higher error rate than e.g. Pfu.
