I donno Rowe ,,, Security systems are not supposed to shut you down once the car is rolling (safety reasons) Most will allow a start then shut down in a couple seconds ,,, or prevent starting completly

It should be setting a trouble code or codes. Get it scanned at any auto parts place and post back here. Hopefully you aren't having an ECU problem.
