I have a 90 300E 3.0 L Base which has ran like a clock until about a week ago. One morning that week when my wife was on her way home from work the engine just cut out on her a couple of times quick, then was fine. Then about 2 or 3 miles later it did the same thing again. I thought it was stumbling so I had her put a bottle of dry gas in it. Two days later I started it and took it for a ride about 20 mins away to see how it ran. It ran fine all the way to my destination, and most of the way back, but about 2 miles from home it did it again. Engine rapidly switching off and back on...tach reflecting that the engine was actually cutting out, not stumbling. I put it in neutral and coasted to a stop along side the road. I put it in park and restarted it...it started up right away and ran fine. I headed out again, and about a mile up the road it did it again 2 or 3 times, then ran fine the rest of the way home (maybe 3 miles more). The next morning it would not start at all. Just cranks and cranks and doesn't even offer to fire. It is getting fuel to the fuel dist block, so I assume it is a spark issue. I am thinking CPS or maybe coil failure. Any comments or wisdom to share anyone? All help is appreciated.......
