Headed out solo last saturday for a ride, filled up at my usual station in town before, I always like to leave on a full tank. Got about 60 miles from home, just cruising along, the normal winding curvy roads of the ozarks and my Heritage(2003) developed a stumble, just like it ran out of gas. It did it again a couple miles down the road. Oh boy, I thought about turning back, but it seemed to run fine after the brief incident. Never did it again, stopped at the parts store and got some Lucas additive for the next fill up. Never did it again in about 200 miles. I'm guessing a little water, but sure made me nervous for a bit.

water in the fuel will give a feeling like you describe. Kind of a just dead second of no power. Does not usually set codes either as its not a miss-fire. Any chance this was a first outing since sitting over the winter ?
Could have has some condensation in the tank ? Ethanol fuel especially is prone to attracting moisture in a fuel tank. A dash of alcohol or some of the product "Heet" will gather any water and burn it through.

If it were mine, I would give it another run and see how id preforms before tearing into anything. If it was something other than water in the fuel it will let you know.

I think the station had gotten a fresh fillup, after I thought about it, I was there the day before and the pumps were really slow while filling the truck. Not the first outing, bought in November and have put 5k on over the winter, it's been very mild this year.

I've had the same happen on my 1991, I believe it was something in the fuel. If your 2003 has a carb, I usually put an ounce of Seafoam (or WM SuperTech Motor Treatment) per gallon and that seems to keep my carb happy when it sits for a week or two. It happened after filling up with Shell gas, even though it's supposed to be "top tier" fuel.

Water shetz happen... I know corny...
When I was a kid and worked at a gas station, the tanks had holes for using dip sticks to check level at the end of each shift. No caps, no covers just a 1 1/2 inch hole to poke the long dip stick through = Guess where the rainwater, or any other damn thing would go - Down the hole to the fuel. When pointed out to the owner we called "greenback" - He said, no problem it just adds to the fuel volume. Ok sir.
