ENGINE STALLS WHEN HOT

2002 Chevrolet Astro • 2WD Automatic •

My 2002 Chevy Tracker stalls when it gets hot; I've replaced the fuel pump. That didn't help (actually seems to have made it worse; stalls quicker). Code says an O2 sensor is bad; Bosch rep says that crankshaft position sensor is most likely the culprit. Any ideas?
