Engine stalls intermittently. Error codes P1391, P0351, and P03220

Engine stalls intermittently. I thought it might be fuel pump but the error codes point me in another direction. The problem occurs regularly but seems to be random. I am replacing the crank sensor. I am also replacing the upstream o2 sensor. Is there anything else I should know or consider?

I have the same problem. Only mine throws p0138, p0340, and p1391.
I will stay tuned to see if anyone has any ideas. I will also let you know how mine pans out. So far I have replaced the crankshaft sensor and it still stalls or bucks when I am driving. sometimes.
