Running git clone from C# Process ignoring input for passphrase

I am attempting to run git clone through a C# process that also passes in the location of the SSH key.
The command:
cd C:\repo-location && SET GIT_SSH_COMMAND=ssh -o StrictHostKeyChecking=no -i pathto.sshprivKey && git clone git@bitbucket.org:location.git
will prompt for the passphrase as expected, however, using Process seems to ignore it so I am getting a "git@bitbucket.org: Permission denied (publickey)." error immediately.
What is also interesting is the Process only returns from StandardError.
Here is the code:
ProcessStartInfo pInfo = new ProcessStartInfo();
pInfo.FileName = "C:\Git\git-cmd.exe";
pInfo.Arguements = "cd C:\repo-location && " +
"SET GIT_SSH_COMMAND=ssh -o StrictHostKeyChecking=no -i "pathto.sshprivKey" && " +
"git clone git@bitbucket.org:location.git";
pInfo.RedirectStandardOutput = true;
pInfo.RedirectStandardError = true;
pInfo.RedirectStandardInput = true;
pInfo.UseShellExecute = false;
pInfo.CreateNoWindow = true;
Process process = Process.Start(pInfo);
process.BeginOutputReadLine();
process.BeginErrorReadLine();
process.ErrorDataReceived += new DataReceivedEventHandler((object sendingProcess, DataReceivedEventArgs outLine) => {
if (!string.IsNullOrEmpty(outLine.Data) && outLine.Data.StartsWith("Enter passphrase")) {
//Never hits here...
process.StandardInput.WriteLine(password);
}
});
process.OutputDataReceived += new DataReceivedEventHandler((object sendingProcess, DataReceivedEventArgs outLine) => {
if (!string.IsNullOrEmpty(outLine.Data) && outLine.Data.StartsWith("Enter passphrase")) {
//Never hits here...
process.StandardInput.WriteLine(password);
}
});
I tried other approaches to get SSH working with git config core.sshCommand but that doesn't even prompt for a passphrase when running from git-cmd.exe.
I prefer NOT to use ssh-agent since there can be a few keys I need to point to.
EDIT:
This can probably be boiled down to allowing a C# process to not eat the prompt for a passphrase and that is the issue with this. Does anyone have any solutions to that?
MORE INFO:
I noticed that even using the command in cmd.exe and redirecting stdout will also prevent interaction. But changing the code to not redirect still skips the interaction.

i see - maybe just comment your code to show the split better between the two scenarios - maybe it's just me but was not obvious at first - thanks

Maybe still not clear. If I use Process to run the command, it will not prompt for the passphrase. It only prompts when running in command prompt or git bash.
