Timing could be too far advanced.

Starter could be going bad, and just not working right when it gets heat soaked.

Is this an EFI or carb motor? If carb, could be fuel boiling.

Is the fuel good?

Is the cooling system working properly? IOTW, just how hot is the motor getting? Running close to overheating could be a factor...

Are you 100% sure the plug wires are hooked up in the right order?

 

Doesn't the EFI inline 6 have a little fan that runs after you shut it down to keep the fuel from boiling?

 

What's it doing when you try to start it?

 

Yeah, is it slow cranking, or does it crank normal speed and just not want to fire?

If slow crank, probably the starter.

If it cranks normal speed, it could be fuel boiling in the rail, or low fuel pressure/weak fuel pump.

 

Thanks Guys I'm pretty sure it's the starter
It's a slow cranker and boiling fuel is not the issue
