1994 Ford Explorer VIN X V6 runs for a minute an dies

Engine problem
1994 Ford Explorer V6 4.0 VIN X Two Wheel Drive Automatic 137000 miles

Prior to the rebuild listed below I had the following condition. The car would have a slight miss at idle and barely noticeable. At highway cruising speed there would be a rattle/ping/knocking sound when I accelerated gradually, but not when I floored the accelerator. Then things got worse, started missing very bad when accelerating, gradual or aggressive didn't matter. If I did accelerate aggressively it would die, but restart instantly, which is not the case now.
--Recently rebuilt the upper engine new gaskets and had valves ground replaced valve stem seals, heads machined and valves ground, injectors cleaned (exterior) and replaced 2 lifters.
Put it all back together and it started first try. Purred like a kitten, for a minute anyway. Each time it starts and at idle it run fairly smooth, but when I increase RPMs to the 1500 to 2000 range it starts missing and dies. No matter what I do it will only run for about a minute. Now after revving the engine to 2000 RPMs when at idle it misses ever so slightly.
Changed the oil, coolant, and plugs. New coolant temperature sensor and purge valve solenoid, plus crankshaft position sensor, coil pack, fuel pump and of course the fuel filter.
Fuel pressure is good and steady 30psi when running and 36psi when cranking. Hooked up a timing light and pulsing light steady. Coil pack tested within within range.
Had the Ignition Control Module tested at AutoZone and tested OK 3 times in quick succession.
I start the car and it runs for about a minute and dies regardless of RPMs.
Hooked up Code Reader KOEO and get the following codes:
111 -- All systems OK
10 -- Cylinder No. 1 low Cylinder balance test
(had compression test and OK, but I've had this code for a couple of years now. The repair shops couldn't isolate why.)
211 -- Profile Ignition Pick-up (PIP) signal
(replaced CKP Crankshaft Position Sensor and no change)
When the car dies it has to sit for an hour before it will start again. If I crank it with the timing light hooked up the light pulse is steady as well as the fuel pressure, but no start. While I'm trying to burn up the starter :-) it will fire a couple of times (because I'm pumping the accelerator?) And then
nothing, but the timing light pulses steady while cranking (attached to plug wire #1).
1) After rebuilding the first start the engine sounded perfect.
2) The engine had set for a week while I did the rebuild.
3) After each start (after rebuild) now it is running progressively worse. It now is beginning to miss even at idle.
