Hello, we have a 753, on friday it was having power issues. If we pushed it at all it seemed like it had not power. We checked everything that is easy, battery, fuel, oil etc. We just serviced it about a week ago, new oil, filter, etc.. Today while driving it down the road it just died. Try to restart it, it does nothing. On the panel it just says input. I searched through here and saw similar issues but not one said how they fixed it. Any ideas?
