7MGTE Heat Soaking

Hello everyone. I have an 87 supra with a 7mgte it's got r35 gtr coils fic 1000cc injectors BC 272 cams and is on an ecumasters emu black with the v3 update.

I'm trying to street tune my car and get it running good enough to take to the dyno. but when I drive it about 10-15 mins down the road it will die and not start back for 3-4 mins. I think its heat soaking but I don't know what's getting too hot. my fuel rails are staying at about 70F, so I don't think its vapor locking. I think it's a fueling issue because it is leaning out really bad right before it dies. could someone look at my tune and logs and give me some advice on what to change or test because I'm lost and don't know what else to look for.

My tune is named tune 28, and the first log is named log 28 and its of dying while driving. the second log is log 28.5 and it's the car cooled down enough to get it to a parking lot, and it idles for about a minute then leaning out and dying at idle.
