Car dies after 8 min.

[JrCRXHF]

Ok last Dec. My car just died and then once it cooled back down and i walked home to get my other car i got it running again and drove it home. I pulled the ecu saw i had a bad cap and decided that i would just put a AEM system in the car because i was going to do it anyway when i built the motor up.

Well now i have the aem system in the car with the following mods

new 255 pump
1000cc injectors
3.5 bar
air temp
boost syn
aem ems
aero FPR
new fuel filter.
blocked off egr.

New coil pack
New Igniter

The car starts runs on really high idle like 2500 rpm then gets down to about 1800 rpm i have the idle screw all the way in.

I can not get the car to idle any less but that does not worry me as much as the car just dies and then will not refire untill the car is cooled all the way down. i can hear the pump run but when i check for spark i have none. I thought the coil pack was bad so i replaced that and still the same problem.

Might check out the CAS. Also, since it seems to be a heat related issue possibly the power transistor.

Edit:
OOps sorry just saw that you put in a new igniter...

i am going to try a new CAS or watch it on the lap top to see if it reads when the car dies.

The high idle might be IAC but it does not go up or down it just idles high.

Since this car has an EMS, there is a 99.99% chance the problem is in the cal file. Idle is too involved to get into, but the no restart after warm up is likely due to the Warm Up Enrichment table, Initial Crank Pulse, or Start Extra vs Temp and Decay.
