Won’t start

Hi. Was out hunting with my grizzly (700 2013), stopped a couple of times and the quad shut down. Re-started easy enough both times. Third time shut done and wouldn’t restart. When shutting down died instantly. Good charge when trying to re-start. Just had tuned up was running great. Thinking fuel pump but I can’t see it starting the other times as far as I understand once a fuel pump is gone it doesn’t re-start. Pete
