My precor will stop moving forward in time and other counts, and the stride goes to zero. The excersing can continue as there is no change in the reisitance or anything else, and the displays still work and move through time, although frozen, number of steps (rate) which is 0, total steps which is frozen, as well as calories, again frozen at whatever number it was when it stopped recording the step rate.
Please follow this steps: Remove the bolts or screws
securing the console to the upright assembly. Lift the console and
confirm that the cable connections are secure. Remove the cover from the
console's battery bay and install a fresh set of batteries. Replace the
battery cover. Detach the ends of the pedals
from the crank axles. Remove the left and right disc shields and side
shields. Inspect the interior of the base unit and locate the flywheel. Inspect the flywheel as it
turns. Locate the magnet installed on the flywheel. Turn the flywheel
until the magnet passes in front of the nearby reed switch. Loosen the
screw securing the switch in place. Rotate the switch to reduce the gap
between it and the magnet. Tighten the screw.

This probably did not happened suddenly right? the problem is not the motor however you can easily check the blue capacitor for peace of mind. with the power disconnected, disconnect one side off the capacitor from the top. with a ohm meter put the 2 probes on the cap,you will ear a temporary beep sound from your meter, then reverse your probes on the capacitor and again a temporary sound that mean your capacitor is good and your motor will run OK.
Your problem is more then likely your run belt and bed assembly. When new, these are coated with a wax of some kind for slipping, has you use the machine wax wears off, and so is the belt. You can see a black rubber dust at the rear of the machine. And so resistance increase when pressure is applied on the running belt.
Just behind the on/off switch where the power cord goes in, there is a auto reset 15 amp breaker that trips when too must resistance against the motor increase the amperage over 15amps. At 7 min/m on your speed setting and if the belt is adjusted correctly with nobody on, the motor pull about 6amps, with someone like me 180lbs, the motor pulls an avg of 10amps with a new belt.
If you have a clamp amp meter you can test it yourself.
2 parts you will need to fix this; 50985-101 (bed assembly) and 36355-101 (run belt 17 X 110) This is real easy to install.
make sure these parts are for your machine model # as they did increased the width of their belt over the years
Since 1998 I had to replace these parts 2 times with an average of 3 people using the treadmill every day. This is a good machine and if everything else is good it's worth it. I paid $300 for these parts, i'm sure if you shoppe a little you can do better.
Have a good one

SOURCE: How do I enable my EFX 544 to give my heart rate
If the EFX 544 has polar Heart Rate attach to the upper electronics your chest strap should be transmitting and the unit should be receiving. If your chest strap is more than 3 yrs old usually the battery will die and needs to be replaced or you have a defective receiver and will have to be replaced

Hello,
Power issues with treadmills fit into two categories: the power
does not turn on or the power shuts off when using the treadmill. If the
power will not turn on, make sure that the treadmill is plugged into a
working power outlet. In addition, you should use a single-outlet surge
protector for the treadmill. Single-outlet surge protectors protect the
machine from any voltage changes that may occur in your home.
If
the machine is plugged into a working outlet, make sure the safety key
is in the keyhole on the console. If the safety key is not plugged into
the machine or if it is pulled out during operation, the treadmill will
not operate.
Finally, make sure the circuit breaker located on
the frame near the power cord is set to "Reset." The circuit breaker is
set to "Reset" if the top of the button is pushed in. When the breaker
is tripped, push it back to the "Reset" position and wait five minutes
before powering on the treadmill.
If the treadmill shuts
off during operation, check the power cord and circuit breaker as
described above. You can also try removing and reinserting the safety
key.
Take care.
SOURCE: on my Precor 956 i the Stop Key prompt appears
There is a micro switch under the red "Stop" button. The switch is stuck and needs to be replaced.
1) Remember that is important key, the cycle of work is a lot, add the dust, environment, etc.
2) Now i will recomend to you, clean with cleaner contact( radio shack or computer store) each week, try to take out the covert and do it, very carefully, disconect the power cord for to avoid ESD. In other word maintenance, with more intensity.
This will be avoid to exchange often.
sincerely.

Ernesto, thanks for the help. I took the entire unit apart and checked all connections. I had also moved the magnet sesor closer as you suggested. So far it has worked through two workouts without reoccurrence. I hope this fixed it, and thanks for the help.
tight very well, and I will no problem. if you have however problem test the magnet with your magnet from refrigerator for atraction and repulsion if do not pass the test, replace the magnet and buy it from home depot more cheap. God bless you
