70k miles. Every few weeks, mostly in evenings after several hours parked, I get a 5 second or so and loud start. Car is cranking strong but never seems to catch and light up. This is rather random. Never happened on cold mornings. Doesn’t happen after 2-3 days of not driving. Is it fuel starvation? Battery seems strong and was replaced less than 2 years ago.

About 2 years ago the dealer also told me to replace coils or something to that effect but I never followed up.

What do you think it is and about what’s a reasonable price to fix?
