The belt is erratic ,This indicates problem with DC board or the motor. Manually push the belt in the direction in which it normally moves. If you have difficulty turning the belt, there may be an issue with the belt/deck friction. If the belt turns freely, there may be an issue with the DC board output.
Use a multimeter to test the black and red lead wires that connect the motor to the power supply. An external power cord connects the motor the power supply.
Most probably its a motor issue.Its got weak,because in most of the cases its seen.But in some cases the board is checked faulty.-------- Get the motor as well as board checked to confirm the fault.
This will help.Thanks.Helpmech.

I'm inclined to think that a tooth could be broken on a gear or flywheel, if equipped. Of course, you would have to partially disassemble it to check or replace it. It could also be a bad rear roller, or bad spot in the belt, and any worn part associated with the rear roller. Take the unit apart to try and identify the bad component, and hopefully you will spot something obvious.
Here's a site that has some parts:
Good luck, and hope this helps.

Error 54 - Target Pulses Lost During Operation... Description... This error is associated with the 5.17 EFX. This error indicates that at some time after the initial start up sequence was successfully completed, the gear motor was instructed to move and no response was seen from the motors revolution sensor. Possible Causes (1.) The F2 fuse is blown.... (2.) Damaged or Intermittent gear motor wiring.... (3.) Bad gear motor.... (4.) Damaged gear motor target... (5.) Bad lower PCA.... Possible Remedies.... (1.) Remove power from the 5.17. Remove the F2 fuse from the lower PCA. Measure the fuse with an ohmmeter. The fuse should measure 1 ohm or less. If the reading is significantly high, replace the fuse. If the F2 fuse was blown there may have been a reason that will cause the fuse to blow again such as; damaged gear motor wiring or a bad gear motor..... (2.) Carefully inspect the gear motor wiring for intermittent or damaged wiring or connections. Replace or repair the wiring or connections as appropriate..... (3.) With power removed from the 5.17, remove both wires from the gear motor. Measure the gear motor resistance with an ohmmeter, it should read approximately 9 ohms. If the reading is significantly low or significantly high, replace the gear motor..... (4.) Visually inspect the gear motor target, if it is ripped, torn or badly scratched, replace the target..... (5.) Measure the voltage at the gear motor during the start up sequence, it should measure approximately 12 V.D.C. The voltage would only be present between the time the sequence was initiated and an error was displayed.. If the voltage is significantly low or absent and the F2 fuse is good (see step 1), replace the lower PCA......
Hope this has helped you.... Thanks...

link for a manual above. It will help.
I would suspect the Motor, and or motor drive circuitry. This is the most common "Fault" If the "Motor" isn't directly faulty, then Often the "Speed Controller" that controls the motor, has gone faulty. all speed controllers, are prone to this type of thing. I really wonder if this type of problem is indeed home fixable? It is my professional opinion, that you get it looked at by a Precor Agent, and ask for a free "Quote" befor proceeding with any repairs, this way you can make an informed decision as to repair or replace.

If using an extension cord try plugging directly into wall. If not check the deck under the walking belt for worn surface (wood should not show) Purchase the silicone lube designed for your model and re lube the walking surface under the belt. The motor is overheating and pulling too many amps and the fix is to reduce friction. (You may notice the problem being more pronounced the heaver and larger feet the user has)

Unfortunately your machine has suffered a "Glitch" and it really isn't anything you have done or that can be "Fixed" by any actions you can do. The unit will have to be repaired at the manufacturers,or agent. The EEprom will have to be reprogrammed or the main board replaced.Sorry.

The power leads Black/red will determine the direction that the motor will turn. If the leads have been switched to the wrong terminals at the lower PCA it will run backwards even if the black and red line up when the motor is plugged in. Check to see if the power cable on the lower board is in the right configuration. I've seen the terminals get switched when a new lower board is installed.

You can test the HR grips to see if the wiring is good all the way from the contact grips to the upper board by doing a test with your meter. Get a meter that can test fuses and beeps if the fuse is good.
disconnect the 4 pin brown connector at the console board, on one side will be some metal contacts.
Touch one end of the meter lead to one wire and the other to the HR contact plate on the handlebar. try all the contact plates on the handle bar until it beeps, then move the lead to the next wire and repeat until all contact plates beep. It all of them beep then your wiring is ok and the problem is in the Heart Rate board in the console or the connection point on the board.
Let me know how it turns out.
