1996 Chevy S-10 I have 2 S-10 that broke down on same day, a

First one is my s10 pickup v 6 Driving down the freeway this morning I was passing a car and lost all power. After I got it home and started looking into it I found that the rotor had basically just broke off destroyed the cap insides. I replaced the cap and rotor thinking that it would fix it. Now when I try to start it I get a backfire thru the exhaust (timing I assume) I have great fire from the coil and also the rotor is turning correctly. Could this be a possible "brain issue"? And or did when I pass the car this morning could something have siezed up and caused the cap and rotor tho break>

Truck #2 93 s10 blazer. While I was working on the first truck my girlfriends daughters s10 blazer basically stopped running. If she would wait 10 minutes it would start back up and go again for approx 3 miles and stall out again. I traded her my last working vehicle and proceeded to dive it home and it would go approx 3 to 5 miles and just stall like no fuel available. I would wait 5 minutes it would start up and go again 5 miles. I caught a ride to go get a new fuel filter replaced that and started it up and we made it down the road like 7 miles quit again then we towed it home. Im not sure where to start on either of these issues. Any idas would be helpful
Thank you
