New battery and car will die restarts with jump drive it and it stops ?

Hello, Are you saying your alternator voltage output is 11.29 volts? Is this with your engine running at 2,000 RPM plus? If so, it is grossly underperforming, as you need more than 13.7 or 13.8 volts minimum to keep everything running and keep your battery charged also. Keep in mind also that voltage output and amperage output are two different things -- check for peak amperage output also. Gut feeling is that you have a charging system concern here. Just beware that the test method may be inaccurate.
