Several issues come to mind. If it’s the original gas tank..... heavy rust or lots of trash. Clogged lines.... easy fix, replace them all. Weak fuel pump...... search for a quality one not Chinese junk. Stuck needle/seat in carburetor........ carb rebuild. Last but not least, out of gas. Good luck.🛠
