One of our 99 V70XC's has a strange problem. The car has 75k on it, and normally runs and drives like a dream.....HOWEVER....occasionally, (probably one out of twenty times) when you go to start it, it will just turn over and not start. If you leave it alone for 5 minutes or so, and try it again, it will fire right up. It runs and drives fine after these little "episodes", but the problem is driving me nuts. Our other XC (also a 99) has 155k on it, and it has never, ever done this.

Any ideas as to where to start??????????????????? As usual, your responses are greatly appreciated!!

Oh, by the way, it is not throwing any codes when it does this either.
