Power transistor is on your intake manifold right by thecoil pack

 

did you figure out your problem with it cuttin out well if you didnt i had the same problem on your crank sensor there should be a red wire cut the red casing off of the wire get a test light and test if you have power if you dont that wire is burnt you need to trace where it goes i never did i ran a new wire from my ignition to the red wire and conected the old one with the new one and then to the crank sensor but then i had to reconect the ignition wire also. Idont know but after a while my ecu burnt up so i dont know if it was my wiring or the ecu was bad to begin with.if tis a gen one the ecu tends to burn up wires for no reason lol.
