Default Car won't run once warmed up...Please HELP!

So, I'll try to make this as short as possible.

I was on my way to the track last weekend, did a 3&4 gear pull on the freeway then the car started missing, what seemed to be ignition breakup, I got it off the freeway and pulled into napa, opened the hood to find oil in the plug hole on #4, I figured "cool, theres the problem" fixed the plug wire hole gasket, put a new set of plugs in, still doing it. After messing with it for 2 hours in the parking lot I said screw it and jumped in my friends car and headed to the track. I come back 6 hours later and the car fires right up, runs perfect. It idled in the parking lot until it reached operating temperature, at 180f it started doing it again.

I towed the car most of the way home behind my buddies truck, got 5 min. away from my house and started it, runs fine. I ripped it home, runs amazing, spins 3rd, runs just as good as ever. Get it home let it idle in the garage for 15 min. It starts running like crap again. It runs perfect until it gets to operating temp. the only way I can explain it is it runs like a car does when its running out of gas.

I'll go over what I HAVE done.
swapped plug wires
new plugs brk7es-11 @ .020 gap
fuel pressure is fine 48psi consistant
new ignitor in the dizzy
new coolant temp sensor
new ecu
compression test = 215 over all 4 (perfect)
swapped main relays
checked resistor box wiring
It does NOT lose power to the coil or the fuel pump

The car is a stock bottom end ls/vtec right now on 110 octane @ 18psi
PTE 880cc injectors
Resistor box
ITS GT61S turbo
Motorola 2.5bar
Stock Ignition system
Dyno tuned on chrome by D. Lee

Any ideas?

Things I thought about, possibly the coil? resistor box? injectors?

I'll try to get a video up later of how this thing runs.
