I have an 07 quad cab 2500 4wd with 5.9 6speed. Today when driving I heard a ding and thought my low fuel light had come on because I was approaching empty but no my air bag seat belt abs parking check gauges and some little red light near coolant temp came on. My tach and spedo also quit. It lasted a sec or two then came back on. It did this several times in about a half mile. Then I stopped at store came back out cranked truck and it cut right back off. Started it back up and pulled onto road and it happened again. I don't loose power but I am worried I have a serious problem. I had my smarty on level six with timing on 4 everything else on default. I don't think it had anything to do with it but I took it back to stock and it did it again since. It had 1 code a pd403 I believe it was. I appreciate any help on this. My mods are smarty SB 3250dd airdog 2 ,isspro EV2 pyro,fuel press,boost gauges a S&B cai and 5" from turbo to 7 inch single stack.

 

My son's 06' did this also,,, but all I remember was the dash guages dying and then come on,,, then a while later it do it again. His was the instrument cluster, I asked the *********** about this the other day, service/mech. told me he'd replaced two on a ladies 07' already and couldn't figure out why they keep going out.

Hope this info helps. Oh yeah, his truck was stock also, in fact he got rid of it about 6 months ago and bought a Dura-Stop
