Oh, I'm 90% certain it'll be a simple fix. I did some minor electrical checks ensuring that previous problem spots were connected solidly. Made sure I have power to the coil. Checked the fuel pump: good pressure and flow. The way it just 'cut out' on me so quickly leads me to believe I have an electrical problem.
However, the sun was on it's last legs, and I didn't want to hold up my co-workers. So, I pushed it to the curb, parked it for the night, and hitched a ride home. I plan to bring a tool bag with me and a wiring diagram in the morning to see if I can chase this down.
None of my friends had a spark plug puller so I couldn't check for spark. I'm almost certain it's going to be ignition related though. And in a worse case scenario, my Crane XR700 will need replacing. I hope not, but it's been in the car for a while. So, it's possible.
