No. He was never the host, guest host or even a guest on The Tonight Show.

David Letterman never hosted The Tonight Show.
Presuming you mean David Letterman, David never hosted The Tonight Show on NBC. He hosted The Late Show on CBS from 1993 to 2015 & Yes, when he retired, Paul Shaffer & the band left the show as well.
Johnny Carson was host of TV's The Tonight Show for nearly 30 years, from 1962to 1992.
Johnny Carson never did "reruns" of his shows; every show was new and fresh. Carson took plenty of vacations, but whenever he was away, one of a number of "guest hosts" would take the big seat. Jay Leno was one; Don Rickles and actress Joan Rivers were others. When Carson announced his impending retirement, NBC tried a number of different people who had guest-hosted the Tonight Show, and settled on Leno pretty quickly. So the straight answer would be "There were no permanent hosts of the Tonight Show between Carson and Leno." My complaint with Leno is that when he took over, he "pulled up the ladder behind him", and never allowed anybody else to guest-host the show, and never allowed new talent a chance to develop their own styles. Like a professor who refused to teach, he tried - intentionally or not - to block any competition from developing.
There has never been a guest who died during a taping of The Tonight Show however, and you might be thinking of the time, a guest named Jerome Rodale died during The Dick Cavett Show in 1971, although the show never aired.
