99' Sea Doo GTX problem

[Watersnake]

Started fine then a short time later, no power. No dash display, nothing. Battery is fully charged, replaced dess post, checked fuses. Checked lanyard on another ski and it's fine. I'm hoping it's not the computer module. Any suggestions? I'd appreciate it. Thanks

Well... if you checked everything... I would be pointing my finger at the MPEM.
