List and describe any other factors which are not addressed in this checklist. We can’t see, hear, smell, or touch your truck, so the more descriptive information you can give, the more likely it is that somebody can assist you.
I've had the truck for a less than a year, the guy I bought it from used it to tow his 5th wheel with it. interior is immaculate. It's had a lot of miles put on it but i've tried to be pretty easy on it. haven't towed with it yet, not even any heavy loads(over about 500 pounds in the bed).
this started last week, it just died. thought my fuel gauge was malfunctioning, and put more fuel in it, but that wasn't it.
ended up pulling th Fuel filter and replacing it, it ran really well for a day and then stalled again. Put a bottle of SeaFoam in it Just In Case, but it died the next day again. now it does it all the time, but intermittently. I *think* its the IP but maybe it's just the PMD? I don't have access to a code reader, does anyone have a different idea, or do you agree that it is probably the IP or PMD?
thanks in advance,
Perry

, wish your 1st post wasn't about an issue you are having, but I'll echo rest of the crew, PMD is suspect., lets do free stuff while we are at it gnds good place to start, which is a good periodic maint. practice anyway.
