92 chevy s10 blaser 4x4 4.3 v6 starts but after it warms up it wont restart till it cools down

15 is coolant temp sensor reading low temp. 45 is O2 sensor reading rich. Older GM vehicles do react to bad temp readings. I would replace it first. This can cause the rich condition for the O2 sensor.

1 and 2 should be your oxygen sensors and 7 is throttle positioning sensor but it could be your coil pack

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...

Had an 84 silverado 305 that did the same thing. Try giving it a full tune up. Plugs, wires... Mine turned out to be fouled plugs. I didn't find that out till after i tore it down & put a timing set in it. Wasn't getting good enough spark.

My first question would be - - are the plugs getting spark?
Did you replace the plug wires in the same order as you removed them ? ?
Is it possible you got the wrong rotor ?

Sounds like air in the system.

could module iin the dist.

replace the ignition control module.

There is a tester you can use that screws on the radiator cap and you can pump it up to see if it has a leak down effect in the system.. This wont tell you where its exactly going but tells you if there is a leak in the head or intake gasket.. probably should start with the intake and replace it and see if it does the trick .. if not then tear it down and replace the head gaskets and or check heads for cracks also.. thanks Jerry

AM temp 55 car started but stalled out after starting. Attempted to restart and did not hear fuel pump. Tried again and then fuel pump kicked in. Checking fuel pump inertial switch and fuel pump electrical supply.
