While driving my Honda Accord LX 1992 slowed down by itself, rpm went to 0 and it would not react to gas pedal for a few seconds, then it drove normally, after a few minutes it did it again. There was a lot of oil on spark plugs. Compression was checked and it is fine. It has 230 000 miles on it, new water pump and timing belt. Oil pan gasket is worn out, it is leaking oil on the ground. What is wrong?

Check/replace the ignitor and coil.
