Engine gets hot and will not start till it cools down

WAIT TILL IT'S COOL, REMOVE RADIATOR CAP, TOP OFF WITH COOLANT DON'T PUT CAP ON. START CAR TURN HEATER ON WAIT TILL HEATER HOT, TURN OFF TOP OFF WITH COOLANT PUT CAP BACK ON, YOUR DONE,

Is the MIL on? When you say HOT do you mean normal operating temperature or above normal?

sounds like your coil is getting hot then when it cools down the engine re starts check coil look for hot spot or touch it see if it is hot it should be cold.

• need to check fuel system when its dead,using the pressure port on the fuel rail.if it has pressure you may have a bad crank sensor
  

Could be a whole host of things. Did you have it checked for codes yet?

If engine temp is not at normal, change thermostat. If it is, check for trapped air in system.
with cold engine, loosen radiator cap & stART ENGINE, RUN TILL UPPER HOSE GETS HOT (meaning thermostat has opened), then see if air burps out of cap. Shut off engine and keep rad full as engine cools down.thighten cap & keep reservoir full.

Did upper hose get hot?

My 2000 accent will stall only when hot and will not start till it cools down.

first thing to replace and cheapest would be the fuel filter ,if that doesn't fix the problem , it may be the fuel pump . GM fuel pumps are in the gas tank, and they have a built in thermo fuse . when fuel pumps get old 60000 miles or so..the motor in fuel pump starts running to hot and the thermo fuse kills the power till it cools down then it will run till it gets hot again note the cool down time keeps getting longer and longer

check fuel psi at fuel rail with fuel tester, if u think its a fuel problem.
prob a spark prob. check spark with spark tester.

CHECK COOLANT LEVEL.CHECK THERMOSTAT.IF TOP RADIATOR HOSE DONT GET HOT IN 10 MINUTES AFTER FIRST STARTING CAR IN MORNING .AND JUST THE BOTTOM HOSE.THERMOSTAT STICKING CLOSE.IF THERMOSTAT FINE.PROBLEM COULD BE CLOGGED RADIATOR OR ENGINE BLOCK CLOGGED OR FAULTY WATER PUMP.
