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.
Dragon Ball GT Episode 39, Baby Put To Rest. Hope this helps!
when Dragon Ball Z started gohan was already born and at the beginning of the great saiyanman saga goten was already born.

Majin Buu killed Babidi because Goku had given him the idea (in their fight) that he didn't have to follow Babidi's orders.
Kid buu was created when vegeta and goku were in buu and remove all the absorbed characters including the overweight buu

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.
Vegeta and Goku worked together to kill him.
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.
they fuse in episode 253 of dbz thanks for the question
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.
um it starts on 210 or 211
Goku doesn't die after Majin buu. Simple as that.
