Answer
Hi Ryan,
I would check to see if it is getting fuel, either by seeing fuel squirt into the manifold, or pressure tester, etc. May be a vaporlock, which could be from a line too close to a exhaust part.
Could also be a heat induced electronic intermittent, like a crank sensor, or the temp sensor.
If there is fuel getting to the engine while cranking, spark needs to be checked, which can be done with a spare spark plug.
Narrow it down to lack of fuel, or lack of spark, and go from there.
Good luck,
Van
