Someone wants me dead? I can't think of who/whom.
This is an interesting sentence. At first glance you would think that whom is called for, because it is the object of the preposition of.
In fact it is not the object of the preposition. The object in the example is the fused relative clause who wants me dead, which has been reduced to who by ellipsis. In that clause who represents the subject; so nominative who is the correct form.
Somebody wants me dead, I can't think of who
wants me dead.
It should be pointed out, however, that idiomatically we would not use the preposition here. In this sort of context think of X has approximately the sense "remember X, call X to mind". What's wanted here is bare think, which has what appears to be the desired sense imagine, conceive.
Somebody wants me dead, I can't think who.
It makes no difference to the use of who/whom, since who still acts as subject.
