IF you have trouble starting - as if the dist.cap/plugs/cables but not motor are faulty - consider the DME relay. there are a couple posts out there on usenet/other on that. however, i do not know if "ran great and then died suddenly" fits that scheme.

relays/fuses are in the black box top right rear of engine compartment. DME relay might be pricey, but easy. usually i think the solder points under the DME relay case crack.

Also check for battery acid corrosion at the battery tray with can damage the engine ECU which is located behind the glove box.
