My brand new 24' R does this as well. Its probably happened 3 times and I haven't even burned 1 tank of fuel.

These new engines are direct injected so maybe it has something to do with pressure loss in the high pressure system. I’m not sure if these have port injection to deal with carbon buildup, but if they do chances are there will be a pcm reprogram in the near future. I feel like with the exception of maybe one user here it sounds to me like vapor lock due to the supercharger but again pcm software update should be able to remedy that as well.
No because ecoboost is also direct +port injected. HPFP on both

It’s definitely embarrassing. My trucks at the dealer now to try and solve this. Even with the video that I sent them, it’s not looking promising on a fix.
Someone at the kids baseball game this weekend as me if I needed a jump. I said mo it's turning over just fine just no spark or compression.

I could be wrong, but thought the predator is port injection only? I know my 5.2 VooDoo is port injection only.
Funny you mention the voodoo, my GT350 has extended crank from time to time if I hot restart it. Happens 1-2 times a summer. I"ve never been too worried about it, and after coming from a cammed LS3, any restart is shorter than a hot restart on a cammed car lol.

I’m pretty positive this is a vapor lock issue, but I’ve been wrong before.
