Could it be a fuel issue?????

120000 miles. No vacuum sound just cranking sound

Was out shopping, stop at a store was in store for 20 minutes. When came out, car started and drove for 2 minutes and car started stalling. The car wouldn't restart, left me and my family stranded. Got a tow home, had a friend put a computer on it. And got error for crankshaft sensor. Replaced crank...
