Can tuning overheat injector drivers?

7730 using $88 mask.
I've installed new injectors (Ford 302), changed bpw vs volts table and zeroed out bpw vs bpw table. I've also set the Multec fixing factor scaler to 0.
Starts fine, runs fine until shut off, then won't restart until cooled off, like 30 minute.
During no-start condition, has spark, has fuel pressure, doesn't have injector signal.
I tested injectors both for ohm and amperage and are normal. The old injectors went back in, thinking I'll start over, but didn't revert back to old tune and same no start when hot condition, so now I'm thinking it's the tune.
Is it possible to overheat the injector drivers with a tune?

I would not expect the drivers to give problems due to the tune. I would expect low impedance injectors to cause problems with a saturated driver.

i really doubt that's your problem

Your probably right.
However, I set the Multec scaler and tables back to where they where before this condition and everything is normal, so it's one of those items for sure. Now that I'm thinking about it, my gut feeling is the Multec scaler set to 0 combined with the reduced bpw tables probably calculated to some ridiculous final pw, hence the lack of fuel injector pulse for hot cranking. I didn't think to hook up the laptop and look at final pw during hot cranking.

Thanks to all who've helped. I think I've found the problem, although I haven't been home to try the solution.
Let me start by saying I'm an idiot :)
I offset the values in the cranking pw vs coolant temp table....and guess what the value was for the last three cells? Yup, you guessed it, 0.00 msec.
I think there's my problem.
Not sure what I was thinking when I changed that table. Duh!

SOLUTION:
It was the suspected cranking pw vs coolant temp table. I reinstalled the 19# injectors and only changed the above mentioned table values to roughly 5 msec and VROOM! Cranked right up hot! Problem solved! Now I can get back to tuning.

yeah, certain masks have quirks like that, the entire speed-density calculation is ignored during cranking conditions and instead a separate set of tables are used. all of the MPFI 60V6 masks do it(I think the SFI 60V6 does as well, but it's been a while since I've looked into it).
