99 crv starting issues

99 crv 300000+ miles, still runs great, starts good cold, but after it gets warm the vehicle cranks but want start, if I let it set for 10 minutes it starts right up.

I have replaced the crank sensor, and timing belt while I had the front cover off, still same issue
have changed out the relay and fuses same issue
Any thoughts here on what might be causing this issue?
