My car has been boosted since Sunday (sc34, revhard mani/dp, uberdata/rc440s), and today it started acting funny. This happened twice, and basically what has happened is Ill be boosting in first gear, and after I shift to second, the car just shuts off and then doesnt wanna start again.

I noticed that my temp gauge was reading a bit higher than normal, and was at about 2/3 of the way to hot, I dont know whether this has anything to do with it or not. After I let the car cool down for a while, it starts fine, and there arent any problems. Im thinking this problem is due to the main relay acting funny because of the heat (90 degree weather, and both times its happened the car was driven hard for 30-45 mins before it died). Does this sound like its the problem? Im gonna test it out again tomorrow and hopefully it wont happen again, but if it does, what are my options to make it stop happening...besides purchasing a new main relay?
