1986 Daytona Turbo Z

The car runs good. . .But. . .After its hot, especially after sustained higher speed driving (on the highway): when I shut it off and let it sit for 5 or 10 minutes and then restart it, it putters, spits and misses real bad. I'll put it in gear and go for a few blocks and it seems to get better/clear up.

What I've done to try and fix this problem;

new plugs, wires, distributer cap/rotor, pick-up sensor, injecters, O2 sensor, coolant sensor, new(rebuilt) 2.2 BLOCK, new(rebuilt) turbo, fuel filter, fuel pump, swapped both computers, repaired vacuum issues, and have installed 3 different injector wire harnesses.
(I still have the dead-miss problem as described above!!)

(no Fault-Codes) 55

Does anyone in this forum know anything about this kind of a problem?
I've been driving this same car for nearly 20 years, I like it, and (now that I'm restoring it) want it to run right (obviously) and I can't seem to figure this problem out.
Knowing how the MOPAR fan base is, I'm sure one of you guys know what can cause this.

If you have any information or know who I should contact, PLEASE let me know!

Thanks
