Question about 2005 GMC Yukon Denali
The truck will stop running all of the gauges also die. The radio and lights never stop working. The problem is temperature dependant. The colder outside it is the longer it will run. I dont believe it is the crank position sensor since the engine temperature is not the primary issue. It is the temperature inside the engine compartment. When it is cold out the truck will run for about 40 minutes, well after the engine is warmed up. If it is hot out i may only make 5 to 10 miles. Once the issue starts I can delay the oncoming shut down by kicking the truck into neutral and keeping the RPMs up until the truck settles back down. The truck will start hesitating this is when I kick it into neutral. This works a couple of times. Eventually the truck will die. After the truck dies I simply open the hood and wait about 5 minutes and it will run for about another 5 to 10 minutes. This works for a few miles then it will only make it a few hundred yards and it shuts back down. So the truck engine loses power, the gauges lose power, the engine chugs then dies. The engine will turn over it simply will not start.
Sounds like a fuel problem, how many miles on vehicle? as a quick fix it would be worth using a fuel addative , you haven't said if petrol or diesel, if petrol get addative that covers the catalytic converter ,having a blocked exhaust system can cause engine to stall also get the OBD codes read as this will tell you what if any sensors/switch's are faulty

Check the B+ cable. If you remove the fuse box cover in the engine compartment (on the drivers side), and you'll see a post with a nut on it, securing a group of red wires. The connector should be a clean copper color. If you take it to a shop, have them perform a voltage drop test on the cable. If it is corroded or burnt, replace that cable!

Please check your engine oil and transmission oil dip stick. Make sure neither is a milky color. If both are OK, check to make sure the carpet on the driver and passenger sides are dry underneath the carpet. I all of that is good, the engine has to be consuming the coolant. Possibly leaking at intake manifold to cylinder head and out the exhaust instead of burning in the combustion chamber.
Let me know what you find and we can go from there.
Also, is the engine running good other than the coolant issue?
