So let met get this. The coil works and engine starts, but dies when you try to accelerate? First thing i would do is run a jumper wire from egine block to the neg battery terminal. if that cures your problem see why the engine ground is lost when engine is under load. If not i would suspect pick up coil or igniter problem. get a wiring diagram and ohm out pick up coil and compare to posted values. igniters rarely fail but your voltage to it might be dropping off.
