Problems with my DP tuner
Well i just put my Dp tuner in a couple of hours ago, when i took it for a test drive, it started up fine but then after like 3 minutes of driving, the whole truck would die, then would start after like 10 minutes, then die after another 3, start after another 10, well you get the pattern, what could be up?

Check for loose connections on the PCM and DP controller. The 10min dead and 3min running is kinda weird. When you installed the tuner, did you make sure the connections on the PCM were good and clean?

If there is an intermitten connection the contacts still has some silicone on the traces or in between them causing the sporadic starts and no starts.
I would double check the cables also to make sure they are installed per the instructions. My guess would be on the first though.

Don't pay too much attention to the time issue. I've had an electrical problem before that I was sure was heat related and the only way to get the truck started was to raise the hood and wait for 20 minutes. I was able to verify it took 20 minutes with the hood up several different times.
Turns out it didn't have anything to do with the hood up, heat or the time. It was a stupid short. The switch or chip itself are the likely suspects as already mentioned.
Wiggle the DP switch or the wire going to the back of it while idling in the driveway. See if that makes the truck stall.
Diane, can he wiggle the chip a bit with the truck running, or does that risk damaging the PCM? I know you don't want to unplug the chip with the key in, I just don't know if the wiggle test would be a no no for the same reason.

Yes check everything and back track. If there is something going on with the switch we will send you a new one pronto.

I just talked to Matt and he hasn't mounted the F5 switch yet he also told me that when he plugged the cable into the switch it seemed loose. He is going to double check that connection in the morning. He is celebrating a friends birthday this evening 
One other thing it had been raining there and he has had the windshield wipers on maybe that had something to do with it also.

Thanks. I've always suspected this, but never thought to ask. I guess that makes the whole loose chip thing a little more scary.

After receiving more info from Jim's post, Jody thinks he has it narrowed down. But asking for traces to be double checked is the first thing we ask when there is an intermitten issue going on. I don't suspect his chip is loose but rather the issue with the cable being loose maybe.

Yes!! Unfortunately.. that can and will happen from time to time. Must take every precaution to ensure it doesn't happen.
