Joyce, you really should charge the battery first. It would be the only way you can tell us or a technician, what the status is. We can't wireless tap into your car to see what is wrong. you need the status and perhaps you even need a technician too.
Look for a vacuum leak at the intake manifold. Spray (flammable) brake clean around the area while the engine is running and look for the idle to change. Also check for a vac leak at the brake booster by pinching the Vac supply line and see if the idle changes.
I have 94 s 10..4.3 v6. it does the same thing have replaced fuel pump and filter,ignition module,cap rotor plugs wires,coil,ground strap...driving down the road jus dies like the key got shut off....for a while when troubleshooting through the parts you could get it to restart.....now when it dies it cranks really hard when trying to restart..ive checked the timeing its fine....if i wait a few min it will usually start...sometimes it will show a check engine light sometimes not......never know when it will happen sometimes jus down the the road from the house sometimes 100miles down the road......sometimes three times in a mile sometimes not for weeks at a time..Wtf...Im ready to shoot it like a lame horse....its a shame too its a sharp lil truck thats a two owner and never spent a night outside in its life...i knew the original owner ...i bought it with 90,000 on it it only has 148,000 now and still looks like new...
Could be a lot of things I would start here. If the engine is shaking at idle or not it maybe the spark plug wires. easy way to check start the truck take a spray bottle and spray a mist on the wires to see if the truck runs worst make sure you stand back while doing this so you don't get shocked.
OK, if it is running rough, does the engine computer record any misfires on any specific cylinders? If so, then start changing parts in that area such as plug wires, plugs, and fuel inj. if this applies.
