how do your plugs look? spark plugs are likely not the problem if it suddenly stopped running, more likely distributor cap/rotor is fried in my limited experience, but it doesn't hurt to change the plugs at $25. the wear on them can be a good clue to your problem- check for deposits/corrosion.

i found the distributor cap was awkward to remove on the m20 as it is jammed right up against the fan housing, but on most vehicles it's an easy check. check for cracks in the plastic cap and burns on the components.
