The stumbling thing is new. Its not dying like it used to but now its stumbling and lost any throttle response that it had. As if it was running out of gas with a carb...pump the gas a little and it gets above 1000 rpm and its fine. Does it in neutral as well. No load. Weird.
Only code is the crank position switch again. Not sure how it lost it after I did the relearn but I don't think it would affect the fuel pressure. Supposedly counts misfires by crank angle. Didn't really notice a difference after it had relearned it the first time. I would have reset it today but its kinda tough to find a place to twist it to 5800 in neutral without turning a few heads. LOL. Besides, it gives me the willies to do it anyway. Lots of rotating mass in that new engine!
