Are you running out of END, just not doing the DPS needed or are you having to use Aid Self too much?
The build looks like you'd need to keep DA stacked or use Aid Self pretty often, which will pull the DPS down to marginal versus AVs with high Lethal Res.

im running out of END, i dont use Aid Self too often. I find myself running this attack chain. GC-SD-DA-GC-GD or
DA-GC-SD-DA-GC-GD
add a miracle + recovery in health that gets you to 3.22 endurance recovery that will give you a big boost.
next make sure you do not kick of conserve power to soon take it down low click it then wail away in fact with marauder on my fire/sd I had less recharge than you do an I slowed my chain just a touch for it to kick in when he was in unstoppable mode and then ramped it up when it came back up

Let's see...
Let's assume you use BU and CP as often as possible.
CP's effective up time for your toggles will be 90s out of every 279.32s. For clicks you have to subtract its own 1.32s cast. So that's 32.22% up time for toggles and 31.75% up time for clicks. It uses 0.04 EPS and 0.47% of your activity time.
BU's up time will be 8.68s out of 48.42s for a +17.9% damage buff at the cost of 2.73% of your activity time and 0.11 EPS with CP down and 0.05 EPS with CP up. Weighted that's 0.09 EPS.
The attack's used are...
GC: 0.924s cast, 117.5 dam + 57.8 * 17.9% for BU = 127.9
SD: 1.584s cast, 274.0 dam with BU factored in
GD: 1.980s cast, 374.0 dam with BU and the proc averaged
DA: 1.584s cast, 128.7 dam
So GCx4 + DAx3 + SDx2 + GDx2 = 15.576s and 2152.1 dam.
Adjust for time used by BU and CP and for a 95% chance to hit and that's 15.576s / (1 - 0.0273 - 0.0047) = 16.09s (that's the average attack chain length fitting in BU and CP when they recharge) and 2152.1 * 0.95 = 2044.5 dam for a 127.06 DPS before figuring in the AH proc. That has 6 chances to fire every 16.09s or an average of 3.73 checks per 10s for an estimated up time percentage of 56.5%. That ups the DPS to 127.06 * (1 + 0.2 * 0.565) = 141.4.
That should be enough if you don't have to use Aid Self too often.
The END from toggles is 0.84 EPS without CP and 0.49 EPS with CP. Weighted it's 0.73.
Without CP the attacks use 2.96 (GC), 3.09 (DA), 6.34 (SD) and 10.00 (GD) and with CP they're 1.64, 1.68, 3.51 and 4.99 respectively. So that's 53.79 for the chain with CP down and 28.60 with it up. Weighted that's 45.79 END every 16.09s for an attack EPS of 2.85.
Add the toggles, BU and CP and total EPS is around 3.7. You're average recovery is 3.15. You should be able to fight for a little over 3 minutes. If you turn off Tough you save 0.16 EPS. So that gets you out to about 4 1/2 minutes.
I'm not sure how to close that gap and stretch that out. I don't think you have DPS to burn given Marauder's Resists and the need to use Aid Self occasionally. None of your attacks are especially good or poor in DPE (37.4 for GD to 43.2 for SD). So changing the attack chain isn't going to help that much.
Adding a Miracle to Health would just about double your time till dry and might be enough. The Miracle and leaving Tough off would probably do it. Unfortunately, I just don't see any corners to cut; it looks like it's spend a bunch of INF or use blue pills.

For making money, Bronze rolls are you friend!
Oh yes, been doing those all the time whenever i get the tickets. Gotten many many stead fast uniques and lots of touch of deaths
Can't get him to the point where he uses unstoppable. I know after unstoppable wears off its game over for him. But I can't fight long enough to get there. Any advice? heres my build.
[edit] trying to do it without using insp or temps
