2015 Gtx 155 starting issue? Main relay been replaced

[Blakemysta]

Hey guys, just got my JetSki out after the winter break, wouldn’t start so replaced battery with new battery and main relay of fuse box. Managed to get it going so decided to get it on the water, jet ski died after 5 mins out and wouldn’t start back up. Got the ski home and it started back up, can anyone please point me in the direction of faults that could possibly be causing this?? Thank you [emoji1360]

Spark plugs almost always first when it’s a 4tec.

Thanks, I’ll try that, I noticed the fuse box has abit of corrosion on it to so I’ll give that a clean up as well thanks
