1998 Hyundai tiburon

I have a 1998 tibarun and have been having a problem starting it after driving it for awhile.
It starts every time on a cold start. But if I go anywhere and park. It still will start,but if I leave it longer than 10 minutes it won't start for about 45 minutes later or longer.
It cranks fine.but doesn't turn over.
I have replaced all the belts,had the water pump tested and replaced the thermostat
,thinking it was to do with cooling,even though I never overheated.
But it doesn't seem to be running hot at all.
any ideas?

Fine to have new belts and what you've done but if it's not overheating you are barking up the wrong tree. It would start if missing all those parts.
Get a code reading then if nothing to say you need to test for what it lack WHEN this happens. Pretty much it would be lacking spark or fuel by the sounds of it so far.
When you know which is missing then you can forget the other and move on from that info,

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
