Ok help needed guys. when I drive my car in the heat for about 30 miles in the heat of the day it starts sputting and bucking and will go dead. and when I try to crank it back up it goes dead. If I let it sit for about 30 mins and come back its fine. This problem is only in the heat not night time or winter. So i put a crank position sensor in last summer and didnt check the pigtails or wires ans it did it again for the first time this summer. what do u guys think

Check the fuel psi.
Datalog it, and see wtf is going on when it dies..

Possible tune issue combined with heat soak? IAT pulling/adding too much timing? But yea, you need to datalog it happening.
