Lifter Pump C2250

[texasmongoose]

First post, go rawze!

Got a 2010 Pete with a fully demandated cm2250 ultrashift 10 speed.
Truck will run for a good 10 mins then dies slow, when checking the water fuel separator I seenothing in the plastic container. No humming noise coming from the lift pump. Checked the harness plugfor juice and itsgot nothing. Im thinking its a wiring problem or fuse/relay issue. Cant find the damn relay/fuse.

Also attached a pic of this circle wire plug thing, the top two wires are connected but the bottom isnt connected, any ideas what its for? No signs on the dash

Any help is appreciated I just started my own Authority and on my first run this happens.
