After driving my 99 Tahoe for a few miles, the gas gauge starts reading
erratically and the engine
starts to stumble. The ABS light also comes on. I have replaced the
VCM and the sending unit. I have also checked all powers and grounds
on the VCM and gas gauge circuits. Any ideas??

hmmm... do all the symptoms start at the same time?

unrelated electrical symptoms that start and stop at the same time,
makes me want to say check the output voltage of your alternator...

good luck
