84 yota ex-cab

I have been noticing lately that my 22re engine will cut out every once in a while. I was pulling some hill tonight and it hesitated for a second or two then it went back to normal. Also, it will sometimes do it when i have the throttle barely pressed, like going down a really gradual hill. I just dont want to break down and not know what the deal is.
Any ideas?

TPS perhaps? I would look at testing and adjusting it to make sure its 100% before you go start guessing parts.
