We cannot be sure, but most likely a person who suddenly looses control and commits suicide, but prior to that made a deliberate act of faith and became a born-again believer he or she is still in a redemptive state even upon falling into sin. Suicide is a sin. We can all fall into sin after we are saved. If a person actually can commit suicide one must question if he or she is truly saved. Nevertheless, the Bible is very strong in asserting that we are saved by grace through faith in Christ. If a true believer has a weak moment, snaps and commits suicide it is hard to believe that the sin of suicide is not covered by the blood of Christ.
