check your battery connections in the trunk (most likely not your problem), and please check your ignition switch. Most likely an ignition switch, hard to catch it when it fails. You should just replace it due to age and wear also. let me know if this fixes. You may also have a crankshaft sensor, fuel pump relay, or main relay intermittently failing but also very hard to catch and replacement is only way to verify repair.
