Not likely, but I would also check the screen in the outlet of the fuel tank. It is eay to do, especially when you have run the tank to almost empty. When I did mine, I used an old refridgerator drawer (white enamel) to catch the fluid and have a visual inspection. This would be a good thing for yor car, even if it was not the root cause. Good luck.
