This has only happened twice over the last month or so but it has me worried. Both times I was down shifting while going into a turn. I would press the clutch down while in third, shift into second and when I tried to give it a little gas I would have no power and see that the engine died. Both times I easily restarted the car while moving though. What could be wrong? I had a tune up done pretty recently. 121,xxx miles by the way.
