problems with my 1jzgte cressida
 

hey, ive got a stock 1992 1jz-gte toyota cressida which i have had for a year or so. lately its been giving me this wierd problem so i thought i might ask as it has the exact same engine as a mark2 supra

when the engine is cold, it starts up, it runs fine and i can drive it around but if i stop and idle for round 30-60 seconds it will shut off. the car will not start again no matter what i do untill a few hours later when the engine is cold. i think one of the turbo is blown so theres no boost (which ill get on to fixing) but i dont think its part of the problem.

any help would be good, thanks! :D
