Hello,
I'm coming in late on this discussion...but...I had a 740 that died with similar symptoms. After a lot of messing around, discovered by accident that the wiring for the injectors that comes up thru the intake manifold had lost its insulation and the wiring was shorting out against the intake manifold. If I remember correctly, the harness comes up in the center and on a quick look, it all looked fine but when you got close to it, the insulation on the wiring was like dust and would just crumble when touched. Take a very close look at this insulation and leave the ignition on while poking around. that is how i found it...had left the key on by mistake and heard the arching as i was poking around. The other possibililty is the hall sensor in the distributor. I had one go goofy and it took me a long time to pin it down. Hope this helps
