Engine cranks but wont start,was running fine,driving down road and just quit

a bad crank sensor will cause car to shut down, and restart in about 10 minutes.while driving down the road.

Sounds like the coil or wire.
Engine running squirt water all over the coil and wires and see if stalls.

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...

sounds like a injector pump to me had a 99 dodge cummins went through three of them in 350000 miles done just like you are describing.

have the crank sensor checked also check the fuel system for correct pressure

check the car computer or control box.sammyc47.

a bad crank sensor can cause this. shuts off while going down road, and will start about 10 min, later with no problems runs fine until it quits again. hope this helps,

I would check the cam and crank position sensor, these are definitely the symptoms of a bad crank sensor.

We had a similar problem and it was the connector that connects the ignition module (bottom of coil packs to the wiring harness. The technician spread the socket connectors and it solved the issue.

yes .check your timeing belt
