cjmarley - i had this issue, spent ages trying to fix/sort, i have about 3500 products, would hit 'confirm' button to run creation of latest feed, but would only get to about 1500 products, max, then timeout and stop, so, first thing i did was to set debugging to true in google feeder admin on zen cart, then i could see where abouts the feed was stopping as when debugging is on you can see all products added as it goes, i found that it stopped in similar place all the time, so, this just confirmed that was a timeout issue, so, i then changed the Max Execution Time to 1000 (it was 300), it seems to work fine now, have created a feed and uploaded. I used previous versions of this add on no problem, a little odd that the new one has timeout issues, but which can be sorted by following above steps...
