95 S-10 2.2L. Sometime when i am driving down the road my S-10 will completely lose power (electrical and motor). The whole truck goes dead. i'm figuring there is a loose connection somewhere, or PCM problem. It died on me the other day and when my buddy came out with the chain and towed me home, we hit a bump and all the power came back on and it started right back up! Crazy Any idea where to start diagnosing would be helpful!!
