Fuel cutting out

I know it sounds like I'm not hearing or believe what your saying. But i'm not there and there is specific reasons for this info. Attach a digital volt meter to fuel pump and watch voltage. Does it cut out then die? Or die then cut out. How many volts are going to fuel pump?
2. With OBD scanner hooked up does it ever lose communication when its running then die?
3. check engine light functions normal. One when you turn key on then goes off?
4. When it dies is it a slow die of engine or does act like someone turned the key off. Shuts off immediately.
5. Exhaust sounds normal?
6. air intake tub and maf hooked up? no holes or cracks in piping?

This is a really odd one to me. So I need those question answered in detail. Including the ones in the quotes

 

I have no power to pump again to test voltage. Check engine light was working properly yesterday. When it dies it's just like shutting the engine off by key. There is no cracks or hold anywhere.

 

Can you monitor live OBD data with your scanner.

 

It's possible they are failing once they warm up. The coil inside the sensor will expand slightly and short out. You might try testing the resistance of the sensors right after it cuts out. I hate to say throw parts at it without concrete evidence that a part is bad.

The idea is if the cam or crank sensor stops working, the ECU won't trigger the spark and/or send the fuel pump signal to keep the fuel pump running.

Do you still have spark when it stops running after warm up? Like during cranking.

 

Read my questions and answer in detail. When its not running you wont have power to fuel pump. I want to know voltage
When its running then dies.

 

If the engine was shutting down from a lack of signal from the cam or crank sensor, there would be a P0xxx code present.

I find it unlikely that there was a broken power or ground wire outside of the area visible outside the cab.

 

Its time for the OP to trade the truck in for an Audi.

 

Trucks fixed bad electrical connections

 

Please elaborate... Were and what connections?

Glad you got it fixed.

 

The prongs on the electrical plug that goes in the fuel tank weren't connecting fully. No one had a plug in for it so I spread the prongs for a tight fit.

 

Cool. Thanks for following up with the fix, this can help folks in the future.
