I have an early 2000's bobcat T 300 with the keyless start system. Out of nowhere every once and a while the machine shuts off. When I go to try starting it the screen lights up and then goes blank almost like it's losing power. Sometimes it'll happen often and other times it won't happen for a whole day. I checked all my battery connections does anybody have any idea. Once and a while it will run for a few seconds and shut off. It does t big or run rough just shuts right off.
