Ok first post, I have owned my 580ck for about a month. Started up and ran great. I decided it was a good idea to get it stuck about 2 days after owning it for not being patient and waiting till summer or winter to drive it near my pond. Long story, got it stuck axel deep for about 3 weeks, finally up and on level high ground. Now she starts and runs for maybe 1 minute and shuts off. I have tried idling up and such but it just shuts off. I am thinking fuel issue, could there be a cutoff value my kids turned or got turned? Could it be a fuel pump and if so how do i test it? what else could make this beauty go to sleep to early? Thank you in advance.
