2004 polaris msx150 turbo question

hey hey, new guy here. I have a question and hope someone can help me. I have 2004 msx150 turbo with about 70 hours and love it. When i first fire it up, the check engine light blinks for about five to ten seconds then shuts off. The ski runs fine, the check engine light does not come on at any other point during a ride. I went on a two hour ride this weekend and rode just perfect except that dern blinking lite for the first five or ten seconds. Any comments or advice would be great.
