Ecu issue

[RubyRanger16]

Been having this weird issue with my 94 explorer I did the manual swap and put a manual ecu in it from rock auto it ran perfect for about a week then it threw a 335 code and have a super high idle of about 1500 but when you push the clutch in check engine light goes out and idle comes down perfectly but then the second you release it idle goes back up and light comes back on, warrantied the ecu got another one again truck ran perfectly for 3 weeks not a single issues but on the weekend was letting the girlfriend practice manual driving and she stalled it, check engine light came on 335 code again high idle for a longer then would come down to 600 but is hunting up and down and again when you push the clutch in check engine light goes out and idle goes perfectly, I limped the truck an hour home had zero power was max 60km/h down the highway then randomly I would get full power back and be able to get up to 80km/h then lose it I was able to keep power for about 30 mins every time you stopped at light would lose power again, I took apart the ecu and it look like there a burnt spot I just have no idea if this is just 2 shitty ecu’s or something truck side frying it. Looking for people ideas what to check or test

I did some back probing at ecu
Dpfe on truck when had issue 8v at idle
Spare Dpfe 1 5.30v idle
Spare Dpfe 2 5.20v idle
All 3 drop close to zero when clutch pedal engaged,

I tested a bunch more circuits that could be connected but most seemed alright
