so my 97 blazer ls 4x4 is stalling randomly, its not throwing any codes but its randomly stalling. when it stalls it doesnt slowly lose power, it just flatlines right where it is. ive been told to check my relays, wiring, plugs, and ECU, any suggestions on what i should do?

 

how often does it do it? And does it do it in diff weather ?

 

Have you ever had trouble with it just not wanting to start? If so, it is possibly the beginning of an ignition switch failure.
