Help

my 2007 Prius died suddenly. Before it died the fuel gauge continued to blink warning of empty after I filled it. Had never done that before. The Prius died less than 50 miles later. A bad hybrid battery and fuel pump was coded. Had the hybrid battery replaced and the car shows no problem codes now. It still will not start. Could this be a clogged fuel filter or bad pump? Does a Prius automatically shut down if it gets no fuel? Any advice will be appreciated.
