Its the fuel pump.
My one did it a few weeks ago. i was driving home from work and as i took off from the lights, after about 5m it would just stop. did it about 6 more times before I got home. took it to the mec and the next day he told me that the fuel pump was not pumping enough fuel at low revs would just cuts out. $300 bux later, and i have not had a problem since
