well there is first battle in which Goku lost and baby almost killed Goku. Fortunately Kobito Kai saved Goku that was on DBGT episode 29. Then Goku appeared for a rematch and with his grown tale he was able to transform into Super saiyan 4 and destroyed Baby. That was on DBGT episodes 33-39.

The first episode of the Buu Saga in Dragon Ball Z is Episode 200 titled "The Wizard's Curse." This episode marks the beginning of the Buu Saga when Goku and Uub, the reincarnation of Kid Buu, have a friendly match at the World Martial Arts Tournament.
well goku fights in an episode called "Battle for the Universe Begins" in the uncut series it's episode 279 that they start in and if I'm not mistaken its episode 280 in the uncut version were vegeta fights buu and the episode is called "Vegeta's Respect".

I can't tell you the episode but it was in the early parts of the Buu saga.
On the last episode Goku fights against uub. (He is an earthling, and due to being the positive reincarnation of the completely evil Kid Buu, his name is a result of reversing "Buu") Goku fights against him in the world martial arts championship, but uub has no fighting skills. So Goku goes to his village and helps to train him.
During the fight with Buu, Goku was dead.
