Question about Honda Accord
The distributor must not heat up. If the distributor is really hot, then the distributor must be replaced.
Your car is not a PC, you do not know that this is an heating problem. Normally, a car only heating problems are concerning cooling system and oil, and when the car is too hot, it does not shut down, but you will get water and oil temp warning lights.
The problem happening when the engine is warm means that this is related to a condition that happens at hot engine. Hot engine will need different air fuel mix, and will use sensors as O2, MAF, AIT etc and powertrain control module in a different way respect to cold engine. That does not mean the problem is overheating! Also, Relay is not 'Soddered' , it is just connected.
Whoever told you this heating up thing was wrong, and the main relay defective will cause multiple problems from start. Please if you want to give me the name of the person that suggested you relay and distributor if you want.
The way to proceed is different , you need to locate the problem.
There are many problems that may cause shut down after a while (have never heard a
Test vacuum system and fuel pump using an hand tool gauge like this: Deluxe Vacuum and Fuel Pump Tester.
Place the gauge on vacuum lines to find vacuum leaks.
Use the tool on fuel pump outlet to find out if fuel pump is failing.
If there is nothing in there , use an OBD-II Code Reader to pull out code from ECM (car computer). This will reveal eventual problems with idle air control valve and throttle position sensor ,O2 sensors, MAF and AIT sensors, injection, distribution etc. And will tell you if there is misfire.
Once you do this tests , you will be able to localize the problem.
Fuel pump problems, vacuum leaks, O2 sensors problems can commonly cause idle going down after ten fifteen minutes. Vacuum and idle air control valve are among the most common.

Your main problem seems to be the distributor by what you have narrated. Sometimes the distributor causes these problems. Even I had similar problem in my Suzuki 800 compact. After the distributor was changed, the problem stopped permanently. It is now almost 60000 miles and it is still going strong. So, try the distributor.
