2007 Toyota Yaris sputtering

[cynnaminkisses]

Hi Everyone,

I have just bought a used 2007 yaris with 105kms on it, and its an automatic. My problem lies when I first begin to accelerate after coming from Park. The car seems to sputter. This is a video on youtube of a differnt car but it does the exact same thing:

I didnt really think anything of it, until I went to my local tim hortons and when I started the car, it started fine then it immediately died with the battery light coming on. It died at least 4 times in a row... the only way I was able to stop it from dieing was I put it in reverse and slowly coasted out of my parking spot then I put it in drive and away I went. I thought it was going to die again once I got to a stop sign.

I would like to point out ive only had this car for 3 days and has no manual with it, I did take it for a test drive before hand and it did not do this. It was also raining like it was today.

I am not mechanic at all, so please be gentle with terminology. I plan on taking it to a mechanic, but I don't really know how to explain this to them or what am I in for...is this a major repair?

Thanks.
