i have an ecu you could borrow if you want to test it

but i would check the connections for the fuel pump ( do you hear it running when it dies ... you could try jumping out the relay or on the reg board is the t4 connector you could ground out the top left pin IIRC, it will by pass the relay pack by the battery ( at least the fuel pump relay there ) you could even rig a led off of the fuel pump connections so you could see it and if you are lossing the power to the pump the light will go out

now there is the chance that the feul pump is bad and after it heats up from running it could lose pressure

now my relay pack works loose every so often and the car dies but i know it so i just push it in and it is okay

but there are many things to check check those and if that does not do it email me and i will send you a check list
