need help my 90 supra turbo keeps shutting off

What part, the one you think is causing the fault?

Usually a fault like this could best start to be traced by checking for a spark when it next cuts out, my bet is that it's losing spark (although more details would help, does it run smoothly normally, run rough just before it dies, will engine turn on the starter but not fire etc)

Another thing to check although unlikely, be good to eliminate it (and only if you DO have a spark) is to open the gas cap & see if it starts then in case the breather is blocked.
