Car falling flat on its face?

[Mensaf]

What's up guys? I met another SVX owner at my gym yesterday, and she has an odd problem. Sometimes she'll be driving, and the car will fall flat on its face, and she'll put it into neutral, turn it off, then turn it back on, and it'll be back to normal. I'm not familiar with transmission resistor issues, and she does have the 16 power light flash, so there is a transmission code somewhere, but I don't know if it's related. Anyone with similar experiences?
