I've got a new 2015 T650 with 35 hours on the engine. I began getting rail pressure codes (76-16) During a long stretch of plowing snow, the machine beeps 3 times and shuts down completely. I have it at a Bobcat dealer as I type this and after talking with them, I'm not very confident that they even know where to start. This machine has 35 total hours on it!! Any help would be greatly appreciated. thanks
