Could be boost spiking. With all the cold weather at the moment, this would be my best bet. What mods do you have fitted, and do you have a boost controller?

If you have a boost gauge fitted you would notice a short period high reading on it.

If you dont have one, beg, borrow or steal one and just plumb it in temp style.
