redtop sr20det wierd problem. help needed!!!

[Hippieperson]

ok heres my problem, my car is cutting off while cruising and has gotten to the point where in the mornings when its cold it will crank right up and run fine and then
just die within a minute of idleing.

heres some background info

the problem started about 2 weeks ago when i had to go the greenville about 1hr and a half from me. about half way there my rpms started cuting out and after about 6
or so times of it cutting out it just died. power stayed on and i was coasing down the road in gear, but could push the throttle and nothing would happen, i dropped
a gear and dumped the clutch and it didnt come back on, rpms rose but i could still push the gas with no result. pulled over and let it sit for a couple mins and it
fired right back up, made it to where i was going and when i was heading home same thing happened about 6 or so times. i continued to drive it as it is my only means
of transportation and it continued to cut out and cut off, till the end of the week. when i went to leave work in the morning(i work 3rd) it cut on and i let it warm
up then headed on my way and about 3 miles down the road it just cut of, no cutting out nothing. tired to start it and it would turn over but not fire up. after
letting it sit for about 30 mins i got it started and drove it up the road to the store where i left it. came back two days later and tried to crank it right after
work with the same results. me and a buddy went and got his trailer and came back around 10 when it had warmed up a little and tried the car again and it crunk right
up but we did notice a fuel leak on the small hose on the fuel rail. drove it on the trailer and drove it off at my house. so far i have tested the ignitor chip and
coilpacks with a volt meter and to my knowledge they tested fine, ive fixed the fuel leak and installed a new fuel filter ive changed sparkplugs and since it was just
sittng did an oil change and installed my ss turbo lines and fixed an exhaust leak i had. ive also fixed the leaky front main seal and cleaned all the elctrical plugs
and my alternator that had gotten hit by oil. after acomplishing all that this weekend i got it all back together and cranked it up tuesday and she ran great, drove it
around off and on all day and when i went to go to work that night she cut off on my twice, same issue not cutting out anymore but just dieing while im cruising, not
under hard load or giving it alot of throttle. well i made it to work and whent to leave in the morning and same thing all over again. im pretty much lost and would
love any and all imput on the situation.

heres the rundown on my engine setup

apexi neo to compensate for the z32
aem wideband, still running stock o2

Ecu codes?

I've never been able to pull the codes from my ecu. The light will blink once then turn back off. I've tried putting it in diagnostic mode then turning the key and I've tried turning the key then turning the knob all the way clockwise holding it for 2 seconds then turning it back. Neither way works

Update.

I tried swapping my coilpacks, ignitor chip and ecu out wid a friend. But since the issue seems to come and go I don't think it was very effective. But we put all of my stuff on his car one at a time and then all together and the issue didn't come up. Leads me to believe it could be within the harness itself. But again ot dosent happen all the time so unless we left it on his car for a couple of days there would be no way to tell and he was kinda hesitate about that.

Also if I turn the key over to acc ( when the fuel pump kicks on). And I go to turn it back off the power will stay on. My turbo timer will show a voltage of between 3 and 6 and i will have to turn it back and forth a couple times till the eccs relay ( I think that's the one ) starts buzzing when it is in the off position. Then i turn it back to acc and the fuel pump will kick on again and i can turn it off and the power will go off. No idea at all what this could be. Done some research and all I could find is it could be a lose alternator ground bit I have checked that and added a ground to it.
