Obviously an electrical problem. . .sounds like a loose connection somewhere

 

[ToyotaNick]

any other places to check other than the battery?

Have you done any work on it lately?

all i have done was change the EFI fuse cause it was melted for some strange reason

Send a PM to Megolfer here on MUD. He had the same problem with his 1st Gen and finally figured out what it was. Hottrod81 assisted with the diagnostics and repair so he may know as well.

Sounds like an intermittent short. Try tracing the wires for the EFI system to see if one is worn through at a spot. I was having problems with a tractor. It would continue to run (diesel) but the gauges would all fail and 4WD would kick in when not asked for. Finally had the whole wiring harness replaced. Found 6 spots in the old harness that were intermittently shorting.

Check for melted O2 wires around your exhaust, have seen this before.
