Cutoff while driving....

[shadmcd]

Got a 99 powerstroke with 330k on it. Its been running great but the last couple days while driving it it has completely shutoff or cutout while driving. Motor dies and instrument panel lights up. While coasting for a few hundred feet it pics up again and no check engine lights or anything on. Runs fine again. Im thinking its something electrical but have no clue where to start . Any ideas?

Pull the valvecovers, and check the harnesses. Typically the UVCH (under valve cover harnesses) will be loose and seperating from the gasket/passthrough. You could build a wedge to hold them in, but inspect the pins and sockets for deterioration first. This is the single most common issue that causes a truck to die while going down the road. If you do this and there is no change, replace the CPS (cam sensor). They are cheap, and prone to failure, but with your symptoms my first suggestion is more likely.

Good luck, and welcome to the forum!

Do all the lights come on on your instrument panel?

Does an engine dying from a sensor/wiring problem do this to the dash?

Sounds to me like the ignition switch might be faulty but not sure.

TY daz and turbo. both ideas at least give me a couple ways to start researching to diagnose this problem. It hasnt doen anything for several days now. The light on the dash only flash on after the truck died while driving down the road. once it restarted they all went out. Having a friend stop by and put it on his computer diagnotic equipment(he's a mechanic) that might lead to further ideas to research. If and when i find the problem I will verify it on here to help others who might have the same trouble someday . Again ty

IPR nut still on?

[danimal4406]

check to see if it is chipped. lower left side by the E brake
my chip went bad and acted like a bad cam sensor with no codes tripping

What is an IPR nut?
And where is it located?
