Hey all I had a weird thing happen this morning. I have an 08 yukon xl denali and just to give background. I had recently had abs ad traction control issues that causes a limp mode. i thought I was going to have to change ecm. I tightened grounds on battery and truck runs great. well this morning I left for work as normal and while coming to a stop she stalled out. she wouldnt start back up. I called for a tow but thenI decided to try to start it again and turned the key and gave it gas and it roared to life. I drove it back home and it ran until I slowed down to pull into driveway and it stalled again. started up the same way by giving it gas and pulled the rest of the way up to property. truck sat there running great while I started other car and when I shut it off it started right back up. no check engine light at all. and only thing on dash is suspension system and service brakes soon. I recently changed caliper and I dont think I got all the air out which is why I believe the service brakes soon is on as the rotors and pads are new front and rear. anyway The stalling is what I am lost on. I replaced the fuel pump last year. I hope that is not the issue again.
