camshaft error -- engines dies -- doesn't restart for about 30 minutes

[jhall-99f350]

The problem I am having is this -- when driving the engine dies, then it won't restart and it doesn't get a 'wait to start engine' light until it sits about 30 - 45 minutes, then the light comes on and I can re-start it. It seems to help if I start it and let it idle for about 20 minutes before taking off. I replaced the camshaft sensor 3 times now in the past 6 months. The first 2 I got from NAPA, today I got one from Ford. Started it, idled for about 5 minutes, drove about 5 miles and it died. It took me about an hour and a half to get home, stalling 2 times and waiting about 15 - 30 minutes to restart each time. I read another thread that sounded similar and his solution was to replace the Injector Pressure Regulator. About 200 miles back I replaced the fuel filter.

Thanks for your help!

Call ford about that CPS and b!tch.

You don't by chance have any of the fuses in the power distribution block replaced with circuit breakers do you? It sounds like something is getting hot and kicking out. I assume it will idle forever but the problem occurs when you start driving? It doesn't happen right after hitting a bump or rough spot in the road does it? That's a long time for a breaker to reset but if it was a weak one maybe? Were you able to check for codes?

Deeslfxr --
I'm not aware of any circuit breakers. I have looked at both fuse blocks -- under the dash and under the hood. I didn't see anything different than fuses there.
It isn't triggered by bumps in the road. It seems to be happening more when I don't let the truck warm up, so not sure if heat is the problem or being too cold.
The only code I am getting it the camshaft error.

I just talked to a local (and reputable) diesel shop here and he said that more codes should be stored in the datastream and they can scan deeper for those codes. His initial thought is that the PCM might be bad. Any thoughts?

[Deeslfxr]

PCM maybe, but I'd check connector and wiring to CPS and PCM closely first. Also I read something here somewhere about setting the depth of the CPS, maybe one of the techs will shed some light on that. What was the number of the camshaft error code?

thats probly what it is

The only error that my FlashPaq gets is P0603 -- INTERNAL CTRL MOD KAM ERROR. I really think this is only a symptom of a different problem. I have put 3 new CPS units in the truck over the last 6 months.

P0603= Internal Control Module Keep Alive Memory (KAM) Error
I don't think this is related to the CPS. I'm not sure what the diagnostic procedures are for this but I'll see what I can find out at work today. Maybe a tech will clear this up for you before that.

603 is NOT related to the cam sensor, it simply means the computer has lost power or has been reprogrammed lately, anytime there is a chip or tuner then this code will usually be there. It is nothing to worry about and should be ignored unless your getting warranty work done.
Your symptoms sound to me like a problem with the PCM or power to the PCM. Maybe try to find a spare one to try out, I got my spare for $75 delivered from car-parts.com
What kind of truck is it?
Is it an early 99 or 99,5
Is it an auto or manual?
IF it is an E-99 and an auto then upgrading to a PMT1 computer might interest you anyway.
