2000 4Runner 4wd intermittent starting issue.

I’ve got a 2000 4Runner 3.4L V6 auto 4wd that is having starting issues. New coils, wires, plugs, starter. Had the fuel line tested by the dealer lines are getting fuel. Just had the dealer swap the starter as well. Did plugs and wires and coils maybe 20k ago. Battery is fine. Ignition is cranking sounds like it’s going to start but just keeps cranking. Only happening every once in a while and it’s not a consistent issue. And doesn’t seem to be getting more often. Seems to happen more often if we had just drove the truck and had it fire for maybe a min or 3 to run onto the store or fill up gas. Any ideas on where I should dive into next?
