I have had Engine Shut off issues while driving and sometimes when I have to stop in traffic. But the latest has me baffled. Engine shut down 200 yards from home. Will not start (will normally start after 10 or 15 minutes), This time, the engine starts, but will not stay on. After two weeks of troubleshooting, I got it to start without replacing any parts.
To start: interior lights switch has to be on "maximum", door open, car starts and stay on. Closing the door or turning the light **** from the maximum engine shuts off and power to door/windows are lost. Read codes are P0561- Cruise Control Solenoid Malfunction; P0101-Mass Air Flow Sensor Signal Failure.
Does this means both of these sensors have failed? I have a feeling there is a common denominator, but I cannot put my finger on it.
I had the oxygen sensor, fuel filter replaced about 6 months before. All fuse are OK. Spark plugs are firing.

sounds like a ground issue i would see if you have this buss and what it looks like, clean your chassis grounds for the battery and pcm as well

Thanks Justin. The weather is good down in Delaware today. I went out, checked all visible ground in the engine compartment. I decided to start with the driver side door. I took the upholstery off, unplugged, clean the connections, forced the door lock lever to the lock position- the engine skipped and held, it stayed on.
After several trial and error, I got the lever to reposition to the open position, I closed the door, turned the engine off, turned the interior **** off and realized I had power to the locks, all windows also. Car started with out a hitch.
I replaced the air filter and erased the codes. P0101-Mass Air Flow Sensor Signal Failure was successfully erased.
P0561- Cruise Control Vent Solenoid Malfunction remained. I took the car for a spin, everything works fine, except for the cruise control.

the cruise could be a separate issue. i have never had to fix the cruise but check to make sure the vacuum tube to it is good and reseat the connections on it as well and see if that helps

Car ran well until March 12th. then went back to the bad habit of loss of power "Engine shut down". Started after five minutes, I have not changed the Engine Crankshaft Position Sensor or the ignition switch. I have checked for corrosion and found none, no corrosions on any grounds.
It would also appear that this is a chronic problem with GM vehicles. I am thinking of going with the switch first.

i would check the wires on the maf. maf can shut the engine down, and might be intermittent issue there.

It was supposed to have been changed by a mechanic friend about a year ago. I will check it out myself. Thanks Justin.

if its fairly new its more likely to be a wire or plug causing the intermittent issue

Cold weather down here. I will check as soon as the weather gets better.

When it won't start....turn key off....disconnect the MAF sensor....now try and start it.....if it starts...turn off...reconnect MAF......see if it starts....if it doesn't, you found your problem....
