After about 10 yrs of marriage, I got the wife to break down last summer and let me get something with two wheels. She only agreed to a scooter, so I got a Vespa GTS 250 but I knew this was just the way in and it would then only be a matter of time
So, after quite a bit of coercion, Santa brought me this:

I absolutely love the bike and still drool every time I see it. I also realize that my opinions are biased, being that this is my first bike and I don't have anything to compare it to.
So lately I've been bundling up and going out so that the bike will teach me how to ride it.
This brings me to the puzzle. I went out the other day to get myself an easy pass, and when I headed out towards home something scary happened. I was getting on a launch pad, eh, I mean on ramp, and had aggressively reached 4th gear when, all of the sudden, I felt the bike lose all power. I thought that I may have accidentally hit neutral or something and I quickly glimpsed at the display. To my surprise, I noticed that it was blank and even more, the bike had shut off. I only looked briefly because I was going about 60mi/hr and with the engine off I was not going to keep staring at the display. The only thing that I was able to catch before the display went completely dead was a big EWS code. I thought the day was only going to get more interesting, but after I came to a stop on the shoulder I cycled the ignition and the bike started as though nothing had happened.
Now I tried searching and though there are many posts on EWS, none were at speed. And wouldn't the immobilizer only affect starting up? What else could make the bike shut off "mid-flight"? I am calmly relating this now, but I don't need to tell you that I did not find it so amusing on the Van Wyck Expwy, and the circumstances could have been much worse. Even with my limited experience I realize I was lucky.
I am sure I am leaving out most relevant details, so if there is anything else I should add just let me know.
Bike has been perfect otherwise, with maintenance up to date according to MAX BMW.
Thanks in advance for any suggestions/advice/help
