time in sonar and when i mixdown my project is out of sync!

sorry my english ill try my best to be clear.  
i mixdown in mp3 my project, and at start both are synchro,
but around something like 50 sec it start to be out of sync (2 sec) between the time in the project and the mixdown (mp3) til the end. 
supposed to be the same?
i mean as example: the 1rst note of my clean guitar is 2sec after in the mp3 compared to my sonar project, and it happen aroud 50 sec til the end, at start to 50 sec all is good. i tried to ear what happenning but hear nothing... its just really really strange.
i disabled all vst, the same. ill try different things again. but if someone have an idea would be welcomed ty.... 
 
edit: i just erased all tracks and buses with vsts, and kept only 1 track clean guitar (vst also deleted). mixdowned, all is sync now. strange thing. what a job to do to find the problem, i have almost 50 tracks 50 busses... grrr..

edit²: found the problem, its when i export in mp3.
i guess the way to fix it is: export in wav, which is ok, then ill try to convert with bigasoft converter to mp3.

edit³: same problem. maybe its because my song is 13:06 long. whatever nothing i can do.

    Why not export as a WAVE.  
      MP 3 encoding can and will change the time. Its not perfect.  
     
    And certain driver modes other than ASIO can put overdub tracks out of sync.

    13:06 of a 24 96 wave is extra big, just for tests.
