If you haven't done so already, you might reset the breaker. Even a 15 year old GE range has a control board and it's possible it's just out of wack from an electrical jolt. Leave the breaker off for about 30 seconds. That's where I'd start - always try the easy and free stuff first. The oven igniter or the relay for the oven may need replacement. Get spouse to lift the oven floor, maybe also take off the drawer and take a look around. He should be able to watch the ignition sequence. It might help. When our 7 year old profile died, we did that - found a bad igniter with burnt wiring and rusted out areas around it down there. That's when the repair started to be pretty expensive. If yours isn't burnt, the igniter is pretty inexpensive and an easy surgery. It's just as likely that the control board is dying and you need a new one. I've never done that kind of surgery, at 15 years old, it's pretty much due though. I always laughed at a relative's jennaire. She spends about $500 every year to replace its board. Just so you know, this is pretty much the entirety of what I know. I got through most of life cooking on old ranges with pilot lights - crap, but I never had a range repaired until this year.

I have a Jotul 600 DV Firelight propane stove that won't stay fired up. The pilot stays lit. But once I turn the stove to on and the flame comes up, it doesn't stay up for long; after about 15 minutes, it just dies; and then it's just the pilot that's lit. Any ideas about what's going on and what I can do about it? thanks!

What he said^^^^^^^,you must continue holding the button down for time stated next to button. If it still gos out,make sure the flame is touching tip of thermocouple. Thermocouple is a wire 3 times diamiter of a round tooth pick leading from near the button to piolet liight. If flame is touching,thermocouple has likly burnt out. Very common. It is inexpensive,available at most hardware stores and can be replaced by average home handyman.

Might be the safety valve but, IME, more likely is that the bake element's hot surface igniter (a/k/a glowplug) has weakened with use. It can glow and look like it is working fine but may not be passing sufficient current for the safety valve to open consistently after the first ignition.
