i have a c4500 kodiak that will start and run for about a minute or so and then just die like u turned the key off . I know its not fuel related like air in the system this is a power problem, when it dies and try to restart it just cranks but if u turn the key off and wait afew seconds and try again it will start and die a minute later i also have codes for u0073 and p0883 and light in the dash come on 30sec before it dies one is a coolant tank sym and the other is a red incomplete circle with an x through it if somebody has any idea please help
