Not getting enough fuel. There are two coolant temperature sensors one for the gauge. one for the computer. the one to the computer monitors fuel. When it fails the engine is slow to start the first try and there is a strong odor of gasoline. The engine will run rough at some speeds and sometimes stall.
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...
Most likely there is a vacuum leak somewhere, check all small hoses and plastic "T" fittings for cracks or breaks, could be a vacuum line to the heater control, power brake booster also, listen for hissing noise @ startup. Happy hunting.
Try remove the six screws that holds the coilpack on the right side of the engine, often corrosion makes grounding fail here and can make the engine die on you for no apparent reason, it might be worth a try
First thing i would check would be the fuel filter. Sometimes, when they first start to give problems, there is enough gas to keep them idling or driving around town, but when you get on the highway they starve for fuel.
