If the problem is in the motor/capacitor/bearings, perhaps the
following test could
verify it.:

Run the motor on "fan only" and see if the same problem occurs,
i.e. the motor
starting and stopping. Make sure the thermostat is in a position where
the gas or
air condx function is disabled...



Here is another possible , often overlooked possibility.

Dirty air filter...... This would prevent enough air from moving
thru the
plenum where the high temperature switches are located. They heat up
and shut off the gas.
I have seen this before. Replacing the dirty filters fixed
it....However, the usual sympton is
that the gas shuts off and the motor continues to run, which is NOT
what you are seeing...
Just thought I'd mention it...

If the unit has an integral air conditioning condenser, if it is
clogged with dust and
dirt, the airflow could be restricted just as with the dirty filter.
This is harder to
clean, but possible, and fairly easy to check --- tho you have to undo
a few screws and
use a flashlight...

Just a couple other things to check before selling your car to pay
for a house call......

Andy,
I see you've been charged $80+ for changing a dirty air filter that
you were too stupid to remember to do.
Not all techs are that way.
As I see it, before you get all testy, this nasty comment makes up for
your last "one liner". Now, Fire Away.
Have a nice day.
