First check for fire at any of the sparkplugs and if you have spark then check your fuel pressure and if its not within specs then replace the pump.
Check the battery cables. If there is no corrosion and you have good connections, then the starter solenoid/relay may be at fault.
Check the cars ignition coil and crank sensor. Either of these could be overheating and causing the car to not start until it sits for a while.
Check the distributor
