Re: What could be causing this

The "new" starter snout may not be the correct one, causing a misalignment between the starter gear and the ring gear. manually engage the starter gear and check for interference or binding. I have heard you can also use a paper clip as a feeler gauge. Is the flexplate new? Is it the right diameter? There are two sizes of flexplates, a 53 tooth and 68 tooth I believe. The starter may just need shimming. The previous posters are assuming that the starter problem and engine dieing under load are related.
