Uddhava Gita section in Bhagavatam refers Bhagavad Gita
SB 11.16.7: On the Battlefield of Kurukṣetra Arjuna thought that killing his relatives would be an abominable, irreligious activity, motivated only by his desire to acquire a kingdom. He therefore desisted from the battle, thinking, “I would be the killer of my relatives. They would be destroyed.” Thus Arjuna was afflicted with mundane consciousness.
SB 11.16.8: At that time I enlightened Arjuna, the tiger among men, with logical arguments, and thus in the front of the battle Arjuna addressed Me with questions in the same way that you are now inquiring.
And then Krishna almost tells same things as 10th chapter of bhagavad gita.
Also here 1.15.30 of Bhagavatam
गीतं भगवता ज्ञानं यत्तत्सङ्ग्राममूर्धनि ।
It says Arjuna recollected Bhagavad Gita spoken in battle field which he had forgotten due to time factor and thus again became master.
