Aerospike shuts off mid flight

[Feelinfroggy]

So on a whim I tried an aerospike engine on a mk2 fuselage and was impressed by the thrust to weight ratio but it keeps shutting off mid flight what did I do wrong ?

Hard to say without having more information-- kind of like if you called up an auto mechanic and said "My car doesn't work, what's wrong?"  They're not gonna be able to say much without having a look at the car. 

My guess is that you're running out of fuel or something, but it's hard to say without seeing your ship.  Could you post  a screenshot?

Welcome

1: Press launch vessel.
2: Left click the resource tab in flight (The Gasoline jerrycan icon in the top right corner of the screen)
3: Then left click "liquid fuel" and "Oxidiser" so that they're highlighted. This brings up UI parameters for all the fuel tanks holding LF and Oxidizer on your vessel.
4: Launch your vessel until the aerospike dies then spam F1 to make a screenshot
5: Go to your KSP directory in which there's a screenshot folder with screenshots you just made.
6: Upload it to a image hosting site like imgur and paste the link of that image here.

Well, without much to go off of here, I'm going to share something I did that was pretty stupid on the off chance that you did the same thing:

Are you sure you chose the Mk2 Rocket fuel fuselage and not the Mk2 Liquid fuel fuselage?  The rocket fuel includes the oxidizer your Aerospike needs to burn with the liquid fuel, while the liquid fuel tank does not, and if you don't have any oxidizer, your resources tab may show you have plenty of LF but your engine won't burn.
