This one is not that easy to figure out. Like Klinck suggested have a look at the coil pack first, The best test is to put a volt meter or test lamp over the two wires that go to the coil pack. The plus should be always on, the negative will disappear when the coil needs to fire. To see the negative go you need to crank it.
Depending on the results here it can also be the crank sensor or even the ecu. Also (to beat Lowrance) check all plugs and connectors as SD plugs and moisture are not good friends.

Hope this helps
