Could be a bad spider injector

If you have a junkyard close maybe pick up a used distributor. the distributor has the ignition control module the coil and the cam/crank position sensor built into it. Id suspect its the electronics in the distributor causing you problems.

When it stalls out yank a plug wire off and crank it. See if you have spark or not. That will narrow it down a little

I was thinking then same thing manifold pressure sensor.if the computer thinks there is boost when there isnt it may be retarding the timing and running it rich.Have you put a fuel pressure gauge on the rail to make sure your regulator is working pro properly?

The express vans with the 5.7 vortex were the same way they would only.missfire under high load at higher rpm. Steep highway onramps getting up to 70. Besides for that on ramp they would purr like a kitten the rest of the day.

Maybe try a slightly higher temp spark plug.

I used to work at a place that had a fleet of Chevy express vans 99-02 2 of the vans I personally tuned up would come back up with cylinder 5 missfire. We ended up paying a shop like 350 per van to replace the valve guides without removing the heads by filling each cylinder with compressed air as they replaced them. Anyways… The missfire was because the spark plug was partially fouling from burning oil. The valve guides and new plugs solved the problem.
