I had the same problem with the 2.42" Display. With the small one (0.96") all worked fine, but with the bigger one it stopped some time or did'nt tranfer the graphic complete in SPI and I2C mode and with both librarys u8g2 and adafruit.
I added a 100uF directly at the display power and made a independed RC reset circuit at the reset line of the display.

After this modifications the adafruit demo worked for hours without trouble.
