2006 GMC SIerra 1500hd dies once up to temperature

by monte86ss on Apr 02 2018, 3:39 PM

I have a 2006 GMC sierra 1500 hd with the 6.0l in it. Truck just started giving me trouble last week. Once the truck warms up it just dies out of no where with no warning. But after about 10 minutes of sitting will fire up and drive for maybe 5 or 10 minutes before it dies again. Could it be an overheating fuel pump issue? or maybe a fuel pressure regulator going bad? No DTCS present. Any input would help

I would check the ignition switch first. Sounds like the PCM is loosing power

Alright problem solved. Ended up having great fuel pressure and had no fuel or ignition problem. With no DTCs present i went ahead and ran a voltage test on CKP sensor. The sensor read 119 Mv with the spec being 200Mv. Replaced the CKP sensor and the truck ran great and the customer was satisfied. Thanks for the responses.

Typically if there are no codes it is fuel pressure or an ignition switch problem. Use a fuel pressure gauge to see if you are actually losing fuel pressure. Also check ignition switch power. We have seen a few times where the fuse box itself gets a bad internal connection too. Usually though it will be fuel pump or ignition switch.
