same shit happen to me in my 99ex and i have not had it for a mounth...got dizzy replaced, new sparkplugs, new fuel filter, new battery, new fuel pimp, and its still not working. My auto guy who is a family friend could not figure it out, so it got back form honda yesterday, they said i needed a new fuse box ??? and a speed sensor. Apperently my car was getting told it was going faster than it was to the ECU..but i dont see how that shuts my car off...but like i said same problem and i still dont have my car back- lmk whta fixes yours..
