Hey everyone having a problem with my 99 GMC van that has a white magic in it although the white magic has nothing to do with the issue the van will not start after you turn it off when it’s hot any ideas?

Fuel pump or gas tank. We had this happen on a Ford Ranger it had something to do with the gas flowing back into the tank or something.

I remember it would start if we turned the key twice to prime it then turned off and primed it again before starting it

Is it turning over? Or is starter having issue struggling to turn warm engine?

Over heating hot? Or warmed up?
Thoughts point at fuel. But why. If engine is overheating hot it messes with the fuel and will give you restart problems. But seems to go away once cooled down. Check anti freeze and thermostat water pump... then go from there.
