I am the inventor of a live patent application which has been altered by the owner of the patent against my wishes. If I withdraw my name from the patent application will this stop the patent going forward?
The answer you are looking for is not straightforward. Where was this patent application filed? Countries (and regional treaties, like the EPO or WIPO) have different rules for that.
For patents filed with the EPO, the consent of the wrongly designated person is required for corrections, except for the case where another inventor is added. The applicant must consent too, in all cases. See Guidelines for Examination, EPO, 2016, Part A, Chapter III/5.6 at http://www.epo.org/law-practice/legal-texts/html/guidelines/e/index.htm
I am not familiar with US rules. If you refer to a US patent application put a relevant tag to your question, maybe someone US-based will pick it up.
