Question about Toyota 4Runner
I keep losing spark on my 86 toyota, hot or cold ,could last 5 min ,or two days . when its firing all cynlinders are go go , and it runs great. but it will spudder and spudder , until she dies , and i will lose spark completely. Coil, or a short somewhere ?
Sounds like a bad coil. But a sensor like a module or an aging distributor cap and rotor are the most suspect. Take off the distributor cap and see if a white powdery substance is building up scrape it clean with a sharp knife... it may run for a few months best to replace the rotor and distributor cap

Try checking your air filter first. Then check your engine ground connection. Change your fuel filter. If it's none of those, it could be a faulty idle control .

when this happens,do you have anyway of cooling the E.C.M. unit to see if this component is heat sensitive?,or possibly the reluctor coil under the distributor tower has a thermal issue,the ignition coil that feeds the tower may also have a thermal issue,because you say after it sits a while its fine again for a time
