engine turns normally but no startup. minutes later it starts n runs fine.

What is your question?

2014 dec. << for the past 2 years a few times now the engine turns and no ignition. 4 times these past 2 years i am told it's electrical and the "computer chip" needs replacing as e/thing runs perfectly on this car..a few munutes after the failed ignition the car starts perfectly. i thought it was bad gasoline, i replaced fuel pump n fuel filter, spark wires n sparkplugs last year. for months it starts like a charm the car is...then once again no ignition but the starter turns the engine, one mechanic told me it was the alarm safety preventing any spark going to the wires. just today after 2 months of excellent performance it once again turned with no startup. tommorow i bet it will start fine. i'm about to get another car. since the two years of this dilemma this has happened 9 times. could it be an old electrical distributor?
