yes on plane it happens less frequently more so under load

Currently in the process of doing this and will be using many of the tips and tricks discussed above. Was super easy emailing Medallion - although part numbers may not be white stickers as they initially mentioned. My part numbers were printed directly on the gauge with a barcode. Once I gave them my part numbers they noted both the lens and the whole gauge are still active and can be purchased (waiting on pricing at the moment). Will see this all turns out. Thanks to all who have contributed here - especially @SkiPablo.

Does it do it while on plane or higher RPM's? Or only dies at idle? I would tend to say the ICM or coil.

Hi wondering if anyone had this same problem. I have a 2010 Malibu wakesetter 247 lsv with the ls3 motor in it. After about an hour on the lake the boat will randomly die and they restart like nothing happened. Once the boat is warm it dies every 15 - 20 minutes. Finally last time it was taken out the boat died and would not restart for an hour or so. The dash all stays on the motor just dies completely or somtimes dies and restarts if at high RPM before dieing completely. Fuel pump has be replaced along with spark plugs with no luck. Any ideas on where to start? Already checked all connections and they seem tight. Could it be a relay going bad? Ignition coil? Ect. Thanks!

Thanks for the offer, but I'll just pick one up, be nice to have around.   I'm probably a couple hours from you down in southern MN.
