So i am looking for any differing opinions here. my 89 FJ62 has done this weird thing where after i drove it about 20 mins to work, stopped (turned off) and then like 5 minutes later i start it again and the battery, brake and AT temp lights come on. I turn it off and on again and all is well. So today it doesn't work i turn it off and on again no luck. I went to go home before the battery died and about 5 miles in the volt meter goes back up and all is well. So i am thinking alternator is dying. Anybody got a different diagnosis?
