The mower gets slower and slower and then stops moving completely. I turn it off for five or ten minutes and it's okay ... occuring more frequently ....

Vacuum slower to allow debris to get onto machine.keep the rainbow running for an additional minute or two when through to allow whatever is picked up to move completely through hose to water basin. It is like plumbing. If you stop the flow midstream it will stay there. Hope this helps.

Dear Sandi,
If I read your missive correctly, I believe your mower is too small for this task.
It would appear to me you could do one of 2 things.
1) mow it more frequently , before the grass grows so tall, ( like maybe 2-3 times a week,) or get a bigger and stronger mower.
Remember too, electric mowers are not usually very strong, but gasoline engine mowers , some are so strong they can mow a forest!
.God bless your efforts.

The drive belt slipping or wrong size

It's probably a worn or loose (or both) drive belt

There could be some type of contaminate in your fuel/lines. Check for that!
Then check your fuel filter. and hoses.

Your carb needs to be rebuilt!

is the belt slipping?is it a auto trans with low fluid level?

Lookfor a light on the dash that says SECURITY or ANTITHEFT. If you see this light, that is a sign of a failed or failing antitheft system, which will disable your vehicle. This link explains

Try and disconnect the battery for ten minutes. During that ten minutes, take some sand paper, and scrub down every terminal metal surface on that battery and the cables to bright and shiny. Then, rehook the battery. Put the key in the ignition, and let it set for 20 minutes. I think that will get it going again.

try checking the belt,might need to be replace are good be the motor over heating

Requires the hyper board to be repaired . Has to be sent to Toshiba, unless you can change around 15 surface mount capacitors, They usually charge around 420 to 450 Canadian
