Drive stopped Thye truck hiccuped at a stop sign and then lost power to move. The ungine was still idling but if pushed on the gas nothing happened, not even reving of the engine. The I shut the truck off and restarted it and it worked.

pedal sensor ....start there..... throw away part

Sounds like you have a cylinder misfire. Is check engine light on ?, Have you had the vehicle somewhere to get a code scan? My assumption is that you have an ignition problem that is causing the rough idle and jerk feeling while driving.
Take the vehicle to a shop and have them diagnose the driveability problem that you are having.

I recommend doing a leak down test. It could be valves or blow by. Also try cleaning the idle air control valve (IAC-V), the exhaust gas recirculation valve (EGR), and fast idle valve (if it has one).

Sounds to me like a bad battery, however the alternator could be bad as well if it's not charging the battery enough to allow for amperage to crank. Auto Parts Forum

No,only on carburated engines it,idles down to the set point,on yours,it's fuel injected,pushing gas pedal won't kick idle down,should go down after a certain amount of time,does it automatically,If you start and drive a 5 mile ride and stop at a stop sign,it should idle at it's set point if there's no engine problems,which may be.5 to .7 on your tac.When you normally first start,it will idle between 1000 to 1200 rpm's,don't push on gas,let idle say 15 seconds,put in drive and go.

The idle is set too low, the alternator is not charging enough, poor battery connection, filthy throttle body, dirty air filter are some of the most common causes of stalling at lower rpms.

Is the clutch properly adjusted?

check throttle cable isn't broken or disconnected.I've had them come off at throttle lever.look under the hood while someone pushes the pedal;car can be off,you should see the cable moving the disc shaped throttle lever.check connection at pedal.

try cleaning the MAF Mass Air Flow sensor element wire in tube with a toohtbrush and carb cleaner carefully. It gets coated with a film. It is in air inlet hose and has a wiring connector on it. Then drive for 15 minutes so it can learn the clean MAF sensor. Is check engine light on?

Removal

1. Remove the air cleaner outlet pipe.

1. Disconnect the mass air flow (MAF) sensor electrical connector.

1. Remove the MAF sensor.

Installation

1. To install, reverse the removal procedure.

Otherwise, you may need to adjust idle air control (IAC).

report on results.

Sounds like a failing MAP/MAF Sensor....manifold absolute pressure sensor or mass air flow sensor. Do you happen to have a check engine light on?
