ive got a 90 si with b20a, 88 4ws tranny steering and axles, exeddy clutch, msd blaster, deleted a/c, power steering. my fans are set to run at all times, the car has been running hot and will shut down whenever it wants, to restart you have to turn off ignition first and then restart.....any suggestions??

 

might be the wirin because on my moms ford exploer it did the same thing and she bought a whole new harness and it's fine

 

go back to you stock ignition setup and see if it still cuts out.

how hot does it get? at idle and while driving? are you getting a Check Engine Light? any ECU codes?

Are you keeping an eye on your coolant level? are you leaking or losing any coolant? Depending on your symptoms, you may need to replace your thermostat(s), flush your system, or replace the headgasket.
