Does it start then stall after driving? try this! pull out the PGMFI Main Relay, remove the outside casing and apply solder to all the bits of solder that are already there (don't join ones that weren't previously joined though) or if you've got some money, replace it! It's a bit of a shot in the dark so I suggest you do the soldering option as your not losing money if it doesn't work.

It solved my problem and hopefully yours!
