Some startup surge is normal.  But if the power use meter is hitting the 
peg 
on the right side, check for binding in the brake, or bearing problems.  
You 
should be able to push the tractor fairly easily when the transaxle is in 
neutral.

Another possibility - especially if the tractor is sluggish - is that the 
drive motor field connections are loose, or the reversing relay is kaputt 
(usually it's burnt contacts).  I'm assuming you have a reversing relay.  
I'm not sure since you didn't tell us what model ET you have.  What is it?

Do you mean that the tractor starts normally, but then stops? 

When it's running, does the tractor seem to have normal power?

By "go into full on the fuel gauge" do you mean that when it stops, the 
"fuel gauge" goes to full?  

What did the "fuel gauge" read before you started the tractor?

How hot does the drive motor get when it's running?

Was the tractor running normally until recently?  When did the problem 
start?

Don't know 'bout the board; I haven't had much trouble with mine except 
for 
a diode that just sort of vaporized once.

Sorry for all the questions, just trying to figure out what's going on.  
(Remote diagnosis is always a challenge.)
