Hope the new DME relay has fixed your problem. Just wanted to add that I had the ignition control module go intermittent in my S some years back, which I'd also heard called the ignition impulse amplifier or somesuch.

In my case the thing would usually cut out while I was in the middle of a turn, though I can remember one or two times it shut down when I stopped at an intersection. engine would stop, tach would smoothly drop to zero and I'd be stranded for an indeterminate time. Fortunately it was mostly happening near home, because once I had ot just leave it for two days before it opted to start again.

My mechanic went through the whole car, redid every ground connection he could find, and logged maybe a 100 miles looking for this one. He'd never seen that module crap out before.
