hi, my name is jerome, i have a 1999 summit x 670, this last summer we took my sled out to ride on the water in centerville, id. the last day we went there i was putting it on the trailer and it died on me. So about 3 weeks later we went to the marsing sprint boat races, i took off and made it just abou to shore and it died on me again, it wasnt overheating, and it didnt look like there was much spark at all after it died, so my question is, could it be an internal coil, or could it be something else that is electronic, my sled is equipped with the electronic DPM controller, any help would be greatly appreciated, thank you.
