what ignition moudle to buy ? ( gm hei 7/8 pin ))

i had an issue with my twin turbo camaro a while back.
i could fire the engine and it would run great for 5-10 minutes and the just die like somone shut off the key. then the issue disapeared so i figured it was something to do with my tune since i was constantly working on it.

well now the issue has come back.
the only changes ive made to the car were to remove the dual vette zr-1 fuel pumps and replace them with dual aremotive stealth 340LPH fuel pumps.
one is on constantly, the other is turned on when boost goes over 12 psi.
ive checked all my wire connections and related stuff and none of it is an issue.
fuel presure at idle is a constant 72psi and stays at 72psi when the motor dies.
so this leads me to the ignition moudle dieing when the car gets hot.
when it does die it wont refire right away,have to wait 5-10 mins then it will fire and run great for a few mins then die again.

so im going to replace the icm the problem is what do i get my first choice is a real ac delco unit, but what about the aftermarket units are they any good? i.e acell mallory or the msd unit
