the other day my 1990 mercury cougar xr7 sc quite on the way home from work and wont start. about 20 km before it died the engine started struggling and loosing power. at 100km/h running about 1600 rpm it struggled to hold its speed but if i throttled up enough for the blower to start creating boost id launched forward and ran fine. when i started slowing down to take my corner it stalled and hasent started since. i have replaced the fuel pump fuel, and fuel filter and still have nothing. does anyone know how to make my baby live again. What should i check next :confused:

I'd check on the harmonic balancer. It sounds similar to what happened when it broke on the 94.
