Saab 2.2tid car loses all power when warm, rev counter goes to zero

Hi my 2.2tid 95 works fine until the temp gauge gets to about half way, then car loses all power, not like the common limp home mode, basicaly tick over power, and the rev counter goes to zero, if left for a couple of hours car starts and runs fine, then will repeat the above as soon as warm, any idea's I've a feeling it could be a Crankshaft position sensor, but cannot find it on the engine block??

    Understand where you are coming from on this, but why would the rev counter go to zero with the engine still running, its go to be reklated to the crank? and the elecronics in it

    The rev counter seems to have a pickup problem and may not be related. Just a thought try running the car with the fuel filler cap removed, this with tell you if you have a blockage in the pipework

2006 hhr loses power. restarting resets power.

Does it lose power or go to limp mode. (second gear)? Being in limp mode makes it feel like it loses power. Takes of slow and does change gears. Have the codes read. Turning it off just resets the computer until it realises something is wrong.

Check your temp gauge, make sure it is not overheating. I am not sure if the '78 was fitted with a ECM, but if it was, then anything that poses a threat to the engine is picked up by the ECM which puts the vehicle in limp mode. This means that the computer actually cuts engine power so that you can limp to the nearest garage to fix the problem and minimise damage to the engine.
However, '78??? I'm not sure I'm in the ballpark with this. Still, make sure it not overheating.

Temp gauge stays cold

If the thermostat is bad (i.e. stuck open at all times), this would allow coolant to circulate in the engine even when it is below the desired operating temperature. This leads to OVERcooling of the engine. You can either replace the thermostat as a first step or remove it and test it -- closed when cold, open when heated above 190-200F.

What is limp mode?

Hi, limp mode or (limp-in mode or limp-home mode)occurs when your computer in your car is not communicating with the sensors on your engine. On some cars(volkswagon Passat for example) If you disconnect the battery then the computer will lose all of the settings and will go into limp-in mode.
The car will have little power and a top speed of only about 30 miles per hour.
The function of limp-in mode is to get you to a place that can repair the car but the car is barely drivable.
