89 Chevy k1500
Truck runs fine for about 20 minutes then the
check engine light will come.on and then it starts
to big down then the engine shuts off completely
after and if you try and start it back up right after it
won't start but let it sit for a few minutes it will
start and then do the same been told to switch out
the ignition coil and go from there any advice
would be appreciated?
