Sounds exactly like what mine was doing until I discovered a clogged fuel sock
filter inside the fuel tank. I pulled it off and added an external filter and
never the problem again.

> shift to OD. Then on the 4th lap I depressed the
> accelerator pedal and the engine sputtered (no
> backfire, more like no fire or no fuel). Drove the
> car back to the show field the engine ran smoothly.
> On my to the motel, I got the same problem if the
> accelerator pedal was depressed beyond a certain point
> of if the engine rpm was above 3000 rpm. Again the
> same the next day driving back to the track. The car
> sat in the shade all day and the ambient temperature
> was about 100 degrees. After the races, I left for
> home, about 100 miles. The car ran just fine. Good
> power under full acceleration up to 4000 rpm in any
> gear even 4th OD. It was still hot on the return
> trip, but not as hot as it was during the laps and the
> trip to the motel the previous day.

> Several days later, I took the car out and it ran
> fine. Visited with some friends, left their house
> about 10 PM drove about 20 miles and the problem
> returned. Turned the engine off for about 1 min,
> restarted it, drove several miles, and it struck
