Traveling at an estimated speed of 70 mph, car lost acceleration. Slowed to a stop. Ignition turns over, battery initiates, no 'fire' to engine. Fuel pump not the problem...


No fire? There probably is fire, but out of time or some liquid (water, oil, PS fluid, etc.) got into the distributor cap and the rotor fire is shorting (sparking) to ground through the liquid.
Check spark anyway, pull a plug cable and set down on metal part of engine ground. Ahve someone crank starter while you look for spark from end of sparkplug cable to ground.
Let us know...
