Engine dies the engine dies when im driving down the road, i have to turn the key to off and then back on before it will start again

Yes. May even start again later after cooling down.

If the engine overheated then the antifreeze may be getting into the engine, indicating a cracked head or block. check for water in oil via dipstick. .

have a fuel rail check done on it. i think this vehicle havs a iddle controal modueal this could be the problem as well.

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...

check the main engine fuse in the engine compartment

Call Auto-Zone or dealer for the code's meaning. don-ohio

if it has a 7.3l then try the cranksensor it,s right on front of engine beside harmonic balancer on the passenger side they are notorious for this and aren,t expensive to replace hope this helps

I've got to be reading this incorrectly...You are driving, the engine turns off...you pull off the road? And then without touching the key the engine re-starts, but you haven't touched the key? Or, sometimes you need to sit there for a few minutes and then turn the key to start it?

that would probalbly fuel filter or a blockage in the tank

Sounds like it may be a loose wire or connection that reacts at a firm bump. I'd check at the starter, and coil. Also check the battery ground at the body and block connections. Hope this will help. Best wishes.
