954 cuts stutters off

Hello, newly registered to the site and first post here. Seeking some help or information about a problem I just started encountering with my 02 954 this past fall and will shortly be sending it to get diagnosed at a powersports dealer unless anyone has some tips or ideas of what it might be...

Hi Guys My 954 shuts off in a split second and comes back on, and accelerates fine... and it only does it in 2nd gear... pretty annoying when overtaking (and dangerous) no lights/warnings comes on. Maby sidestand og clutch?? some ideas??
