Pool pump starts, shuts off 10 sec later

I have a 1HP, Split Phase, 115 volt motor. I used last year with no problem, this year when I first started it, it starts & then shuts off in 5-8 seconds. My husband left out in the New England weather instead of storing it in cellar like we usually do. I do not have a capacitor, so that is not the problem. I tried it 5 times the other day and each time same problem. When I called husband outside to show him, he touched the motor & it was hot. He wants me to buy new motor, which is difficult due to covid19. I just feel the motor is not shot or it wouldn’t turn on. Any advice? Just paid $1,050.00 to have pool filled (have a well) and I’m worried my water will get nasty before I can get new motor. Just don’t understand what’s going on.
