Sounds to me like a combination of a firmware issue and your end gcode in whatever slicing program you are using. I suspect that your end gcode contains an unbuffered command, but the firmware is (incorrectly) not waiting for all moves to complete before executing it. What firmware are you using, and what do you have in your end gcode?

If my theory about it being a firmware bug is correct, then you may be able to work around it by putting one of the following commands at the beginning of your end gcode:
G4 10000 ; this should wait for 10 seconds
M400 ; this should wait for all current moves to complete
The idea is force the machine to wait for the moves to complete before it executes the G28. Alternatively, try replacing the G28 X0 command by G1 X0 F5000.

OK, looks like your the firmware running on your printer electronics has a bug then. It should wait for existing moves to complete before executing any commands that will disrupt them, other than M112 (Emergency Stop).
