Ok so the motor is brand new with all new ignition componets, crank sensor and map sensor are brand new. Spider is also brand new. I put the new motor in last week and she ran perfect up till yesterday. It would start and run perfect for a few minutes and just cut off like someone turned the key off. It done this long enough for me to get it back to the shop. Now it will only turn over and not start at all. Its not trowing any codes.

 

make sure all your ingnition components are hooked up correctly. check plugs, wires, dist, battery, etc. could also be a fuel problem. not enough fuel getting into the carb/tb to keep it running or get it started.
