Camshaft and crankshaft position sensor

I've have a 03 trailblazer and my service engine light has came on. During the time service engine light was on, vehicle has stalled 2 times. Both times it stalled when shifting from 3rd into overdrive. I took vehicle and had codes scanned. Came back as both camshaft and crankshaft position sensor. It seems odd for both to be bad at same time. Vehicle runs fine other than stalling twice. Service engine light has now went off. Any recommendations for this problem would be appreciated.
Thanks

You need a full scan to look at the complete picture, just the codes will really not do it here. The correlation between the 2 sensors may be skewed and this requires more in depth diagnosis.
