03 ram 1500 hemi 4x4 quad cab long bed shuts off while pulling out/driving

[joseph_edkin]

I can drive this truck for an hour sometimes with no problems and other times it will shut off 10 times in that same hour. The guages will all go to 0 and back up over and over while driving, mostly shuts off while pulling out of a stop sign seems like trans slipping then shuts off. When it shuts off it acts like I just shut the key off... no bucking or trying to run just instantly dies. Wait about 10 seconds and the dummy lights on the dash light back up and it will start right back up. also sometimes it will do it while trying to start it... it will turn over for a split second and then act like you shut the key off. Wait a few seconds and try again and it starts right up. I already replaced the ignition switch, crank shaft sensor, transmission control, transmission input and output shaft sensor. All relays.

Does this happen just after filling the fuel tank to the top?

My 08 hemi 1500 did that AFTER I had the factory recall "anti splach back" installed in the gas tank filler tube. If I don't let it get completely full, then zero stalls. If I fill it to the brim, I will get stalls as soon as I back off the accelerator until I have used about a gallon of fuel.

No it doesnt seem to matter how much fuel is in the tank, it has done it from a full tank all the way dow to a quarter tank, also I replaced the fuel cap thinking maybe that was an issue

Check the ignition switch, the wires going to the switch could be loose in the plug or the switch could be going bad.

I replaced the switch already, I was going to check connections and possibly run new power and ground to the switch in case it is dropping somewhere but is that a good idea? And if so should I splice into the existing power and ground so it back feeds to the entire line or cut and put the new wire directly in?
