While driving about 60-65 my 300M will unexpectedly die; no sputtering, hesitation, or warning. All electrical still functions (lights, AC, radio, horn, etc). After a short period, it will start right up like there was nothng wrong. At first when this happened, I could not even get the starter to crank - nothing- no sounds no clicks - nothing, until it just suddenly starts. Today it occurred again (3rd time) and it did the same thing, but when I got stopped on the side of the road, I could crank the starter/engine, but it would not start. It took about 5 minutes of letting it sit, and then it miraculously started right up and I drove 15 miles to work. This has happened at roughly the same point on the highway during my morning commute (within a mile or so of the same spot every time). No check engine light, no indication that anything is amis until it just dies.
