Starts and drives but dies

This 1.6 L fuel injecxted automatic Mazda has been a nightmare. It starts runs/drives as soon as I turn off the ignition and start it again for about 1/4 mile then when I step on the gas it dies again but will idle down the street fine for a time but eventually stop again. then it starts imediatly and drives off again. the head was resurfaced and got the compression up to 125-150 on all four. it does not miss at all but does the same as before the head was reworked. I have replaced the distributor, computor, fuel pump, fiddled with the timing, attempted to locate an air leak by spraying starting fluid but none is apparent, has anybody got ideas.
