Can't control small probe launch

I've got a very small probe rocket that I'm looking to launch to harvest a bunch of "Return science from X location" contracts- in this case, Kerbin orbit.
However, when I try to launch the probe, the rocket becomes uncontrollable in a strange way. First, the engine begins to shut down- the throttle is decreasing as if I were holding shift, though I'm not. Secondly, after the engine has shut down, the craft suddenly spins completely out of control, even though it was easily in control before. This starts to occur at alt 3km, speed about 330m/s. I've tried various combinations of the wings- it's a cheap vessel so I originally went with 8 basic fins, and I also tried 4 control surfaces, but it didn't make a lot of difference. Finally, the engine also randomly re-ignites after the craft starts spinning, which as you can imagine puts a terminal dampener on my aspirations to orbit this craft.
Why is my probe rocket's engine shutting down and then wreaking havoc with my stability?

Given that the commenters couldn't reproduce the problem, and I effectively prevented it by simply throttling back for the first few kilometers of atmosphere, I'm inclined to believe that this is just some random glitch in the game.

How do you control probes in KSP?
Hold down Shift to increase the throttle (necessary for liquid-fuel engines like the one on this ship), and then tap the Space bar once. The support structures release and up you go! Every rocket launch happens in stages, and each stage is triggered by tapping the space bar.How do I control my rocket in KSP?

Probes are craft whose command modules have zero crew capacity, modules generally known as \u201cprobe cores\u201d. Probes can perform missions and can often more easily reach places that manned vessels either cannot reach or cannot return from (at same cost or tech level).Can - Mother Sky (1970) [HQ]

Answer 2
is it possible that you had your control point upside down? at launch you would see the brown pointing up instead of the blue on the nav ball. Mechjeb does not work when this is the case.
