Stumbles @ 90...

[1TROUBLED1]

ok,ok I know I am not supposed to drive that fast,, But the last trip heading north on I-5 the truck started cutting out around 85 to 90 mph. It felt like the lift pump was going again, so when I pulled into town I checked the pressure and everything was fine. Does anyone have any ideas why this is happening??? Is this a common problem??

What's you presure at 85-90?

My last lift pump was good a idle but went to 0 under load.

How old is your fuel filter?

I think I know what it is, I saw it on "Cops" TV show the other night. It"s caused by the Police throwing the spike sticks infront of your truck

I don't know what the pressure is at that speed,, I have a fairly new lift pump and a Holley blue as a pusher pump. At idle pressure is about 23 lbs. (Pitbull) As far as the "Cops" episode,, well it wasn't me this time,,, but I have had the unfortunate experience of meeting a few on I-5.
