Most likely the bar coil on the stator plate went bad, my blaster has done that 2 times in the last 3 years. Running fine, shut it off and it wont start, and no spark when I check. You can check it with a ohm meter, I think 192 to 228 ohm between the terminals. That is for a blaster i think a banshee is the same. You might want to check with a dealer though. If that is the problem, I dont advise you to buy from RMSTATOR. I had terrible luck, sent the wrong one the first time, 2 weeks later I got another one, which was bad when I got it..
