We ran out of diesel while running the generator yesterday, we opened the valve to share diesel with the main tank and today we wen't to start it, it took a few tries but after running for like 10 minutes it stoped on it's own, we started it back again and it works but after a few minutes it shutdowns, oil pressure is normal and water temp is fine, should I bleed air from the lines? Change the fuel filter?

Thank you
