55. The way Trask set up to kill Clark in Corrina's story
Trusting Me, Trusting You works when he escapes. (No spoilers)
56. Clark gets exposed to Lex's new green-stones cufflinks before getting punched by Tommy Garrison (the cyborg boxer). His neck is broken.
57. Superman is banished from Metropolis due to heatwave and nobody wants him to help them anymore. He moves to the Sahara desert and becomes a hermit.
58. Lois is actually captured by aliens in Contact. Superman leaves Earth (I don't know if this counts as 'death') to search for her and never returns.
59. Spencer Spencer's doctor is successful in weakening Clark's immunity and removes his head, but his Kryptonian body cannot survive without a brain and therefore dies when attached to Spencer Spencer's head.
60. Spencer Spencer's doctor is successful in weakening Clark's immunity and removes his head. But Spencer Spencer forgets that Kryptonite kills Superman so the piece of Krytponite he used against Clark kills his new body.
