OK, I'm willing to cop to not having had much to do with non-computerized engines over the last 20 years so it's possible that I'm just not groking today's problem properly, so here goes:
Had The Beast out for a bit of exercise today.
Dropped ten gallons of gas in the tank (gave me half a tank by the gauge) and hit the freeway north bound. I was running up to the local rest stop to dump the waste tank, so It was about 5-6 miles of freeway, with the last bit uphill from Fife.
Dumped the tank, visited the rest rooms and got back on the freeway. All the time in the rest stop the engine had been idling.
As we were coming up to speed, the engine started to stumble, then died. I coasted to the shoulder, tried the key, and the engine fired off right away.
Went up to the next off ramp, circled around and back on the freeway south bound. Now we are going slightly down hill, every thing is fine. Down thru Fife, flat, then up the slight grade past the Tacoma Dome. Soon she starts to stumble again. I'm just keeping a light throttle, as I'm approaching my exit, but there is still some stumbling. Onto Hwy 16 and on around it is all fairly flat, no problems all the way home.
Here is what I know; I had about half a tank of gas, while some of it was a few months old, ten gallons was fresh.
This only happened on a slight up grade, probably less than 2%.
(I don't even want to know what would happen on greater)
The fact it started instantly after dieing (I think) eliminates a blocked filter or pickup.
I could think a vapor lock after idling at the rest stop, but we were only in the 40s today, and that doesn't explain the repeat.
I'm open to suggestions.
Oh, and just to add to the fun, the Wife is sitting in the other seat.
