Engine shuts off after warmed up and code P0336

On my van I can start it just fine. It will run fine while it idles and even in drive until it warms up then it shuts off. If you are driving and it does it it bucks. I have chase wires everything is getting correct voltage and have replaced and checked the following: crankshaft position sensor, MAF sensor, alternator, plugs, wires and fuel pump. I have cleaned the throttle body, I have checked the air filter, checked the fuse box for burns of shorts, checked the ECM for both. I am getting a p0336 code it's for the crankshaft position sensor, it's brand new says low voltage. I am lost here. I can't buy a new car, can't drive it to a shop. I have kids no way to go anywhere. I don't know. Thank you for your help. My next question is, if the battery is bad will it cause everything to to get the correct voltage and cause that code? Could it be the camshaft sensor? If you can throw me a few things to look at I feel like it's something really small. Could the engines exhaust have a plug in it the catalytic converters are not on. It still doing the same thing it was with them on. I just need some ideas on this. Can't afford to take it to a shop because I can't afford to have it towed there. I am at a complete wall thinking about taken some auto mechanic classes once I get this fixed and becoming a master mechanic. I am frustrated with it.
