Did it about 30 times on that trip but started fine and while annoying it got me home. I did have 2509 code so I cleaned all terminals and put in one new battery then, but it still acted up after all that. Then I drove 2 years around home with no long trips more than an hour or 2 and no issues at all. So I took it to Georgia and about 9 hours into trip it starts doing it again. I again took off all terminals and cleaned and had batteries tested at Oreilleys auto parts and both load test good. But it blinks out.... sometimes it did it 3-4 times in a row and then go 100 miles without doing it. Then once and 40 miles without.... Then it really got bad, did it 8-10 times in a row and really never wanted to run right so I got off interstate at a truck stop and let it sit overnight. When I started it in morning it fired right up and blinked once idling and tried to leave it wont run 2 seconds without doing it... multiple times in a row so it still sits at truck stop cause I didn't wanna get stranded on interstate. I did recheck all grounds and battery terminals again and its all good. I'm waiting for a buddy to come tow me home. Gonna get home and try to figure it out, I hope it isn't the ECM but if so does anyone have one off eBay that is "REBUILT" FROM ONE of those places??? JUST wondered if they were any good.
