What are the code numbers please? I have seen the MAF short out and cause stalling, I would unplug it to see if it makes a difference. Here is the location and how to get the codes for us:

That is hard to say until we figure out what the problem is. I could be as simple as a loose fuse and as involved as a rebuild PCM. Did you try unplugging the MAF sensor? Also, what are the code numbers?
