truck keeps dying
truck fires right up but dies right away and all the guages stay on but the oil pressure stops working
The oil pressure not indicating isn't strange, if the engine's not turning then neither is the oil pump, so there is no oil pressure to indicate. Attach the car to an OBD2 fault reader and see what pops up, it might be something simple like a large vacuum leak or an ignition fault or something a lot more complicated.
