Stalling? Restarting

[yzair]

Driving down freeway yesterday and it was like someone had reached over and shut off key and then turned back on almost instantly. No SES light and truck runs fine. This happened like 3 times in 100 miles. It would occur when I would have to take foot off gas to slow down for slower car and then put my foot back on gas pedal, Not kicking it down just resuming original speed around 60 -70 mph and in O/D was not towing anything. 2001 f-350 7.3 super duty

Mods / AIS / severe duty air filter

No I went ahead and changed cps but still does the same thing. I get code for low boost ? but I dont think that has anything to do with the problem. I have a leak At up pipes so thats probably the low boost issue

The motor actually shut off or just went to 0% throttle? Could be throttle sensor.

tach needle drops to zero and bounces right back like turning a light switch off and right back on it happens in a blink.

Could be CPS still, possibly IDM, bad PCM connection or PCM, or even UVCH.

wouldn't these items throw a code?

Mine threw a code then the ses light went out. Has done it since

You'd think they would. But not always for exactly that item. More like a subitem.

You've got a stored code.

Well problem is getting worse gradually, now it shuts off for a couple seconds and starts back up. No ses, no codes, no smoke, no engine shake nothing. The best way to describe it is like turning off a light switch and flipping back on?
