Might want to change out your crankshaft position sensor.

I drove my car to the store, and when I wanted to leave, it wouldn't start. KNOWING that if the CPS is failed, you won't see any rpm indication during cranking, I quickly determined THAT to be the case. Since these OFTEN will work again when cool, I went to the nearby Burger King and had lunch. Then went back to the car, it started right up, and I drove it home. I already had a CPS in my parts stash, so as soon as I got home, I changed the CPS out.
No further problems. I now carry another new one in my parts stash that I take on trips. It only took about 15 minutes to change out. I don't normally carry my special tools with me unless I am traveling, but if I take a trip, then everything goes in the box that tucks under the trunk interior floor liner. All my special sockets by function, special wrenches, spark plug socket, etc. etc. If I use something for the Crossfire, I just put it in that box, and it stays with the Crossfire tools. When I do a job, I write down all the socket and extension requirements on 3 X 5 Cards, and they go in the little tools set as well. I also include such stuff as the routing for the water pump belt, all the torque requirements, etc, etc. It has saved my butt several times while on long trips. Turns a major problem into a 10 minute side-of-the-road repair and off I go!
