next time it happens try spraying water in mist form around the throttle body if it bogs, replace the throttle body gasket. if it doesn't bog you may have a bad wire wait until dark start the vehicle have someone feed the fuel very slowly and watch for arching from a wire it will be easy to see when it is dark, replace that wire.

My question is why you replacin the postive wire?

With that much mileage everything is worn! code p1345 which is crank shaft camshaft position error code.If the distributor moved that is why the code is present. The dis. in these trucks does not control ignition timing it controls injector timing (it is the cam sensor).

Open up the hood, remove the headlight covers then remove the cross mounting thing to the grill. Then gently push bottom of the grill down and out. Then the grill should basically just pop out. --------------------------------------------------------------------Truck & Heavy Duty Diagnostic tool

go to any auto parts store and look for pb blaster.spray around where the hub and rotor meet .let it soak-maybe overnight.then use a block of wood and a heavy hammer(if you dont want to damage the rotor)work your way around the rotor.clean everything with brake cleaner after.PB Blaster is what us pros use.

if you done everything the same and the rotor still wont come off then it is siezed to the hub so yes you'll have to knock it off, try a light tap before you pound on it.

Here is a picture of the brake light switch. Also at this point just buy a new connector and splice it on, much easier.

check your fuses and if their ok check your bulbs it rare but seen then both go out before.If there ok the next thing would be that the brake pedal is not seperating the distance that it should from the switch being that you have new rotors and brakes.

Try opening up the caliper with a flat screwdriver thru the opening in the middle of the housing.pry on the rotor and pull towards you to push the rotor back.That should loosen it up enough for you to get it of the rotor.If that dont work you probably got a stuck caliper and have to release the brake line and do the procedure again. GOOD LUCK

I own the same 3500 GMC 6.5 diesel truck with the same problem. We replaced the brain under the upper turbo hood and it fixed it pronto. No more shutoffs

It seems you have a sort circuit in the wiring or the switch......

normally you have 2 types of shorts, 1 is to earth and this causes the fuse to blow, indicating a fault and preventing a fire.

The second one is a short to power, where the circuit remains on, despite the switch being turned off.

I would suggest that the park light switch is shorting out.

If you are not familiar with electronics, I would prefer you seek an auto electrician to do the job.

Does it have a trailer hitch and wiring? If so, check to make sure connector is not shorted out and double check your fuses and/or replace fuse. It may look good but I've seen some that were burned out of inspection view. You might also want to trace wiring back to brake lights, just in case snow or build up pull connectors apart.
