Hacker a30-10xl-v2 900kv problem

I have a Hacker A30-10xl-v2 900kv motor and am using a Turnigy Trust 70a esc and recently had problems. Everything worked fine for months, but then today when I went out to the field and tested my motor before flying, it just suddenly started behaving strangely. I am using a 11x6 folding prop.

The system just seems to not have any power. The motor beeps and sounds just like it use to, there was never any smoke or burn smell. However, the motor now spins only at a fraction of the speed it use to and provides little thrust. I tried a different esc and got the same results so I believe my esc is fine.

Any idea what could have happened? Are these Hacker motors known to be flaky? I've tried different batteries as well with the result. Any help would be appreciated.

Hacker motors are good motors and yours was working. Are you able to check the windings on your motor for resistance? Even though there was no burning indications, still could be a short or a broken wire.
