Engine/Transmission (1998.5 - 2002) Truck dies at highway speed

[MBrakey]

To give you some background. I own a '01 2500 4x4 auto pretty much stock except for a K&N Filter and a Banks Big Hoss chip. The truck has 130k on it and is primarily used to get me to work and back. I put 27k miles on it last year just for that purpose. Yesterday, while on the freeway (75-85mph) the engine stumbled and died. The only way I could restart it was to hold the accelerator to the floor. otherwise nothing. I changed the fuel filter at the next exit. The old one looked pretty clean but changed it anyways. When I got home, I noticed that the familiar sound of a lift pump(?) was not present before startup. I am assuming that that is the problem. I do not know if it is an actual bad pump or if it is not getting any voltage. Any suggestions or If my assumptions sound wrong, please help.

Sounds like the lift pump is at least part if not all of the problem. No fuel pressure gauge?.

Thanks! I think we got her fixed. Now on to the transmission... .
