you seemed you covered most possibilities but lets check some more

is the map sensor reading at operating temp is between 0.8 to 4v ?

what are the fuel trim readings ,long term and short term at idle at operating temp ?

what is the fuel status ,open or closed at operating temp ?

maf sensor , if you rev and look at scanner live data ,does have smooth transaction of voltage ?

if you unplug maf sensor while running does engine dies or stumbles or no change ?

lets start here and we go from there

so few seconds and it dies ,

only fault is p0068 ?

is the anti theft triggered on and that is why it is dying ?

if you spray starting fluid while starting or before dying will it stay running ?

what are are you losing fuel or spark or both when dying ?
