Goodman GMT090-3 won't stay ignited


The house is cold. Turning the heat off then on and also flipping the breaker gets the fan to turn on but burners won't stay on. Took off the two panels, indicator light is on (no blinks, so no issues per the troubleshooting sticker). Once I put the lower panel back on (pushing on the safety switch) the blower turned on, the unit ignited. All four burners burn hot for about 20 seconds then the burners go off. The house is 59 and I've got the therm set at 69. Kids teeth chattering.
Hope one of you samaritans can help because the van just broke down too. I need a cheap fix. On the other hand, if I need a pro, then I need a pro. Just don't want to spend it if Iit's an easy fix that a reasonably handy guy should be able to handle.

Also- are Goodman furnaces reliable?

Clean the flame sensor with fine emory paper or clean steel wool, sits in front of one of the burners and should look like this:

Thanks so much Yuri! I know, it's early in the game but it's been cranking out hot delicious air for 15 minutes. I read that advice in other posts but your photo and directions made it brain dead simple. THANKS!!! I would love to buy you a beer or two in appreciation.
