I have had the p2509 code pop up twice before (within the last 2 months) and today I got the p2509 and p0088 code as well. Every time this happens I will be driving too work, get about a mile from home and the truck will lose power, check engine light will pop up and I put it into park, restart the truck and continue driving to work with no other issues. Get to work pull out my Smarty Jr. and clear the codes. Fuel pressure seems normal and so do my other gauges, except when it goes dead of course. Today it did not go all the way dead but it wanted too and I thought it had, pulled over, put it into park, noticed it was not dead and drove to work with no more issues. Got home scanned it and those two codes popped up on my Smarty. Any help with this issue would be appreciated. I plan on looking for the AC? wire rubbing next to the oil filter and fixing that (hoping it is just that) and cleaning the connections to the batteries. I checked the batteries and they are holding a charge, just out of ideas. Thanks again. I do remember that the days p2509 happened it was days when frost was on my truck and I believe I put on the rear/mirror defrost button as well as my heater and defrost, don't think this would matter...

I had this happen as well and it was the Batteries. take them and have them load tested even if they show to be charged they couold still be bad under a load. also make sure all the Battery connections are clean. Your grid heater is kicking on with the cold mornings and the Batteries can not keep up and the EMC will shut the power off seeing the voltage drop.

Also, if just one battery is bad, replace both so you have 2 new batteries. Good luck
