[QUOTE="turbotodd, post: 481750, member: 7376"] there was a run of prematurely failing fuel pumps around the tail end of that timeframe. The complaint was exactly as you describe. Dies with load applied, and sometimes intermittently. In order to diagnose, you would need a fuel pressure gauge attached to the rail or better yet a way to datalog fuel pressure. Barring a supply side (fuel tank pickup, line, filter/separator) issue, I'm leaning toward a fuel pump. Call a dealer with your serial number and ask them to check if there's any bulletins or recalls for your particular motor's serial number. You might get a surprise. [/QUOTE]
