Can anyone give me some advice. I have a brand new L3560 with the cab which I love. Or at least I did for the first 15 hours running it. Just came back from two weeks away and went to start it up. Starts up fine runs for 30s then quickly shuts down. No alarms or warnings. My super helpful dealer said no problem for $640 they will send someone out to pick it up and then see what is wrong. It's probably something simple but I can't figure it out. Any advice would be appreciated. I dont want to send it all the way back to the shop for something simple.
